Its depth of color and enhancement of the wood grain is a significant advantage for projects where aesthetic quality is paramount.

Durability: One of the most compelling reasons to choose oil-based polyurethane is its durability. It forms a hard, protective layer that is resistant to scratches, stains, and general wear. This makes it an ideal choice for high-traffic areas or furniture pieces that will be used daily.

Versatility: While oil-based polyurethane is particularly favored for wood projects, its versatility allows it to be used on a variety of materials. It can be applied over paint, fully cured epoxy, and other finishes, making it a flexible option for complex DIY projects.

Application Tips

Ventilation: Due to its strong odor and higher VOC content, ensuring good ventilation is crucial when working with oil-based polyurethane. Always work in a well-ventilated area or wear a respirator to avoid inhaling fumes.

Application Method: Oil-based polyurethane can be applied with a natural bristle brush, a foam brush, or a clean, lint-free cloth. Each method offers different advantages, but all require a steady hand and a methodical approach to ensure an even coat.

Drying Time: One of the trade-offs with oil-based polyurethane is its longer drying time compared to water-based alternatives. It typically requires 24 hours between coats, though this can vary based on humidity and temperature. This longer drying time can be a benefit, allowing more time for the polyurethane to level out, reducing brush marks and imperfections.

Finish Options: Oil-based polyurethane comes in various sheens, including gloss, semi-gloss, and satin. Choosing the right sheen depends on the desired aesthetic effect and the project's specific needs. For example, a glossy finish might be ideal for a dining table that you want to stand out, while a satin finish could be better for a bedroom floor that will see a lot of foot traffic.

Maintenance and Care

Maintaining the beauty and integrity of an oil-based polyurethane finish involves regular cleaning with a soft, damp cloth and avoiding harsh chemicals that can damage the surface. For floors and heavily used surfaces, periodic recoating every few years can help maintain the protective layer and keep the wood looking vibrant.

This rapid drying time accelerates project completion, a boon for both hobbyists and professionals alike.

Low Odor and VOC Content: Water-based polyurethane emits a significantly lower odor compared to oil-based varieties. Its low volatile organic compound (VOC) content makes it a healthier choice for indoor environments, reducing exposure to harmful chemicals during application and curing. This feature is particularly advantageous for projects undertaken in less ventilated spaces, ensuring a safer crafting experience.

Clear Finish: Unlike oil-based polyurethane, which can impart a warm amber hue to surfaces, water-based polyurethane dries clear, preserving the original color and grain of the material. This characteristic makes it ideal for projects where maintaining the material's natural appearance is desired, such as on light wood species or over vibrant paint colors.

Ease of Use and Cleanup: Water-based polyurethane can be easily applied with a brush, roller, or sprayer, making it versatile for various project types. Cleanup is straightforward, requiring only soap and water, which simplifies the process and minimizes the need for harsh chemical solvents.

Application Tips for Optimal Results

Surface Preparation: Proper preparation is crucial for achieving a smooth, flawless finish. Start by ensuring the project surface is clean, dry, and free of grease or dust. Sanding the surface with fine-grit sandpaper creates a smooth base that enhances adhesion, followed by a thorough wipe-down to remove sanding dust.

Application Technique: Apply thin, even coats of water-based polyurethane using a high-quality synthetic brush, foam brush, or a sprayer designed for water-based finishes. Avoid overworking the material to prevent bubbles and brush marks. Between coats, lightly sand the surface with fine-grit sandpaper to ensure a smooth finish and wipe away the dust before applying the next layer.

Environmental Conditions: Temperature and humidity can significantly affect the drying and curing times of water-based polyurethane. Ideal conditions are between 50-90°F (10-32°C) with moderate humidity. High humidity can slow drying times, while too low humidity may cause the polyurethane to dry too quickly, potentially leading to uneven application.

Curing Time: While water-based polyurethane dries quickly to the touch, it requires a longer period to fully cure. Allow the final coat to cure for several days before subjecting the surface to heavy use. Fully cured polyurethane provides a durable, protective finish that resists water, chemicals, and wear, preserving the beauty of the project for years to come.

Criteria for Choosing the Best Polyurethane

Durability: The endurance and robustness of your product may be impacted by your decision between oil-based and water-based polyurethane. Oil-based polyurethane might be a preferable option for furniture that will be subjected to a lot of wear and tear, like dining tables or floors.

Application Method: Your comfort level and the project's specifics can dictate whether you use a brush, spray, or pour-on application. Spraying polyurethane, for instance, is ideal for complex shapes and detailed work.

Aesthetics: The finish of the polyurethane (gloss, semi-gloss, satin, or matte) can significantly impact the look of the completed project. Consider the overall style and use of the item to determine the best finish.

Compatibility: Not all polyurethanes are suitable for every material. For example, certain types are better suited for wood, while others may be more compatible with materials used in mold-making and resin casting.

Encapsulation by Way of Clear Casting Resins

Posted by EnvironMolds , Labels: , , , Friday, March 31, 2023 3:55 AM

Embedding a special object or even a biological specimen in a clear casting resin is an easy way to preserve it for eternity! The clear quality of the resin ensures that the object stays visible on all counts.

There are casting resins and then there is clear casting resin! Indeed, while polyurethanes are being used for making different types of resin castings, there’s something special about clear resins!

What sets clear casting resins apart from the rest of their ilk is that they can be used for encapsulation. Indeed, the clear quality of the resin makes it perfect for embedding different kinds of objects. They will stay clearly visible from all angles and look beautiful while at it.

The objects to be encapsulated can range from leaves, flowers, buttons, shells and other small objects to even special keepsakes like a stamp, coin, ring or a photograph. The casting process is used to make different objects like paperweights, key rings and jewelry that look both attractive and unique due to the items encapsulated inside them. The same technique also serves well for making point-of-purchase displays, rapid prototypes, special effects, sculpture reproductions, giftware, etc.

On a more serious note, science also falls on encapsulation for preserving biological specimens, like insects, plants and even small animals.
 



How to do it?


Clear casting resin is available as a two-part polyurethane casting system. It is usually mixed one-to-one by volume. Special molds are available that are specifically designed for clear casting. However, most artists prefer to make their own molds to ensure uniqueness in every feature of their casting.

While the mold can be made of almost any material, silicone molds are considered best. Especially, molds made with platinum-cure or condensation-cure silicone material will help preserve the clarity of the casting.

The casting process involves pouring the mixed clear casting material into the mold before gently embedding the object in the desired manner. Prior to this, it is important to degas the clear resin as it is prone to trap air bubbles. A pressure pot will work well here and the casting can be left to cure in the pressure pot itself.

Color can be added to the resin during the casting process – in the form of pigments or dyes. This can create a wonderful marbling effect in the casting.

All clear casting resins cure at room temperature. The cured cast will be UV resistant and non-yellowing.

Points to note


Encapsulation is not as straightforward as simply placing the specimen in the resin casting. The object has to first be cleaned thoroughly. It should also be completely dry. Leaves and flowers will have to be dried to remove the moisture content, and preferably coated with a preserving chemical. Biological specimens call for careful handling.

When it comes to the choice of clear casting resin, the number one option is obviously AquaClear Clear Casting Resin. Available at EnvironMolds, this is optically clear and cures to a hard and non-yellowing resin.

The Essence That Makes Polyurethane Resins What They Are

Posted by EnvironMolds , Labels: , , , , Tuesday, March 1, 2022 12:45 AM

 When it comes to the resins, polyurethanes are the most popular and versatile of the lot. Here is a look at the properties and benefits of polyurethane resins which work in their favor for making molds and casts.


Resins are the most commonly used type of casting materials. While synthetic resins are of different types with specific properties and uses, the polyurethane ones turn out to be the most diverse and versatile of the lot.

When it comes to polyurethane resin casting, there are options like fast-setting resins, slow-setting resins, clear resins, opaque resins, foaming resins, semi-flexible resins and more. These are two-part formulas that are usually mixed in equal quantities to form a hard and durable plastic.

 



These resins can be used to produce an array of products. The liquid is poured into the mold and will capture all the details to form a rigid cast. It should be noted that the resins have low viscosity which works well in the shaping and casting in the most optimum manner. The material also flows well which allows it be mixed and processed with ease.

After casting, the resin sets quickly and can be demolded in a short period itself. There is minimal shrinkage in the process and it displays heat resistance as well. Again, note that the resins lend themselves well for casting very small and thin-walled items which still come with high stability. It sets quickly and can be demolded in about 15 to 20 minutes itself.

The best part is that the resin is receptive to additives like fillers, color pastes and even inhibitors. Water clear casting resins are commonly used for making jewelry like pendants, earrings and bracelets by encapsulating leaves, flowers, buttons, stones, pictures and other keepsake items.

It is noteworthy that the finished polyurethane casts display excellent chemical, oil and grease resistance. Even the abrasion resistance properties are exceptional which ensures that the casts do not tear easily.

However, artists need to keep in mind that polyurethane resins tend to be sensitive to moisture and ultraviolet light. The latter can even cause yellowing, especially in the water clear resins. It also emits a strong odor during the curing process which can become a health hazard.

Special care has to be taken in the pouring as clear resins are prone to bubbles. Casting in a pressure pot will suffice here as the pressure compresses the trapped air till the resins set to a hard plastic, not leaving any space for the bubbles to expand once again.

When it comes to AquaClear Clear Casting Resin, it can be easily sourced from EnvironMolds. This is a storehouse of all types of materials, supplies and equipment for making molds, casts and life casts. For instance, it is not just about the resins alone, the website also provides access to resin pigments, medium and more. Additionally, there are photo luminescent pigments and a complete line of skin-safe body paints as well.

Playing with Temperatures for Better Resin Casts

Posted by EnvironMolds , Labels: , , , , Thursday, December 16, 2021 3:57 AM

The temperature of the resin as well as the room should be on the warmer side to ensure that the resin castings cure properly and are free of bubbles. Following are some tips on how to get the temperature right.

Resins come as a two part system – the resin and hardener (or catalyst) have to be mixed together in the specified ratio to make it workable. Here, it is not only about how the two parts are mixed, but also the temperature at which they are used.

Indeed, the temperature of the resin mix as well as the room will determine the quality of the resin casting!


Manipulating the temperature


Resin cures best in warm and dry environments. In case the resin is too cold, it will become thick and may not mix properly. Moreover, the mixing procedure will tend to trap air which will show up as pesky air bubbles in the cast. The resin also fails to cure properly in a cool room and will turn out soft, bendy or with cloudy streaks.

On the other hand, when the resin, hardener and the surroundings are warm enough, they will support the chemical reaction that is essential for the curing to take place.

So, if the resin and hardener are not warm enough, they need to be heated prior to use. The trick here is to place the bottles in warm water for around 10 minutes before mixing. Do not use too hot or boiling water as it will accelerate the curing, thus shortening the pot time. The resin may start curing even before it has been cast!

Another point to note is that the bottles should be dried properly after removing from the water as any droplets of water that fall into the mix can again affect the curing.

In a similar vein, the temperature of the art studio should be maintained around 70℉ to 75℉. If the space is cooler, it is advisable to turn up the heat in the room and close the door prior to starting the casting process. This will even dry up the room a bit. However, ensure that the temperature stays stable as any drop in the mercury can again delay the curing time of the resin.

Some artists even go as far as warming up the mold with a heat tool to ensure a perfect casting! Another option is to use a ‘hot box’ to keep the air around the curing resin warmer than the temperature of the room. Then again, do not overdo the heat either as the resin will cure too quickly in hot surroundings.

EnvironMolds is a one-stop shop for everything to do with mold making, casting and life casting. It offers top quality materials, supplies and tools including all types of resins and polyurethanes for making exquisite casts. The range covers jewelry resins, clear casting resins and even a special formula that can increase the size of the casting by 160%.

Tips for Working with Materials

Posted by EnvironMolds , Labels: , , , , , , , , Tuesday, April 27, 2021 1:56 AM

Mold making and casting is an easy job as long as you abide by the rules and instructions. Following are some useful tips that every artist should follow, irrespective of the type of mold or cast.

The world of mold making and casting opens up a veritable treasure trove of materials – each with their own specific characteristics, methods and usage. The commonly used options are clay, wax, alginate, moulage, plaster, gypsum, concrete, polyurethanes, rubbers, etc. Artists can try their hand at different materials and play around with different options depending on the type of mold or cast they are making.
 


Following are some general tips that beginners should keep in mind when working with almost any kind of material for making molds or casts:

  • Every packaged material comes with its own set of product literature like TDS (Technical Data Sheet), safety data sheet. Always read the label and other product information carefully before using the said product.
  • Work with materials that are already at room temperature and ensure that the room is at room temperature as well.
  • Stick to the prescribed methods and techniques – like mix ratio, type of release agents, compatible materials – at all times. At times, there may be other simple provisions that can make a world of difference. For instance, alginate requires the use of soft/bottled water; using hard water even unintentionally will render the material into a lumpy mess. It takes experience to deviate from the given methods to tinker with the viscosity or other features.
  • Some materials are suitable for certain applications and other options may not work as well, depending on the model, mold-making/casting material and other factors. Choose an appropriate material for the task. Seek advice from experts if needed.
  • Always shake or stir components thoroughly before use. Sludge can sit at the bottom of the box while oil tends to float on the top. Shaking before use followed by proper mixing of the components together is crucial.
  • Always mix a small amount as a batch test at first. It is better to get a feel for the material before mixing in large quantities for the project as it can end up as a time-consuming and expensive mistake.
  • First try your hand at making a small mold or casting, use a small object as a test model before moving on to larger molds or castings.
  • Keep the pot time and working time in mind. Avoid pouring delays as this will add to the working time and can affect the quality of the mold or cast.
  • Before pouring, check if the sealer and release agent have been used, if required. Also check the mold/mold box for leakage before pouring the material.
  • Wear gloves when working with any materials. Some materials may require the use of mouth mask, safety goggles and other additional protection.
  • Use clean and good tools for any project. Assemble the required tools and supplies before starting the work.
  • Follow the indicated set time and demold time to the T. Else, the mold or cast will end up distorted/deformed and unusable.
  • Do not hesitate to ask any questions to the experts about the clay mold, resin casting, cold casting, alginate life casting, etc.

All the best for your new project!

Safety Precautions When Working With Resins

Posted by EnvironMolds , Labels: , , , , , Tuesday, January 14, 2020 4:00 AM

Resin is a commonly used material for making different types of casts. It is fun to work with especially when making artistic jewelry and other casts. However, some safety measures are needed.

Resin is a viscous material that slowly hardens and sets solid in the form of a plastic. It comes in various types – like epoxy, polyester and polyurethanes. Resin casting is very popular among professional artists and novices alike.

The uses are varied ranging from artistic jewelry and faux metal casts to small parts in manufacturing industries to 3D printing to even gluing things together.

While resin lends itself well to many a use, the artist has to handle the material carefully and keep the following precautions in mind:
  • Some resins are considered volatile chemicals and should not be allowed to come into contact with the bare skin. Even the catalyst can prove to be risky. Always wear protective gloves when working with resin. Use a plastic apron to avoid ruining the clothes with spilled resin.
  • It is better to wear safety goggles and use a respirator when working with large quantities of resin. This will help shield against the noxious fumes.
  • The work area should be properly ventilated with open windows and an exhaust fan.
  • It is better to spread some wax paper on the work surface before using resin. As resin will not stick to the wax paper, it will be easy to clean. The dried resin can be simply peeled off from some materials; else it can be cleaned with rubbing alcohol.
  • But never use the alcohol or other solvent in case the resin comes in contact with the skin. Try to wipe it off immediately with baby wipes. Sticky resin can be scrubbed off with soap or a pumice stone.
  • Maintaining the ideal environment is crucial when working with resin. 70°F is considered the standard temperature as the resin fails to cure properly if the studio is hotter or cooler. Therefore, an air conditioner or heater may be required.
  • The resin and hardener should be measured accurately using measuring cups. Do not go by ballpark approximations as it can again affect the curing of the resin.
  • The materials should be mixed carefully and thoroughly using stir stix for a couple of minutes to ensure a uniform mix. However, overmixing can also introduce air bubbles into the casting material.
  • Some air is bound to get trapped into the resin and will show up on the surface of the cast. This can be popped with a needle or heat gun. Casting in a pressure pot is ideal for eliminating the air bubbles.
  • The resin is likely to attract dust or animal hair while it cures and will end up ruining the resin casting. Keep the studio clean and cover the cast with a clear dome while it cures.
  • Above all, follow the manufacturer’s instructions and safety precautions to the T.

Polyurethane or Silicone – Which Mold Rubber to Use?

Posted by EnvironMolds , Labels: , , , , Monday, November 25, 2019 3:36 AM

Polyurethane and silicone rubbers are the most popular mold making materials because of their versatility and ease of use. So, which of the two options will actually suit a particular application?

There are a variety of mold making materials for capturing negative impressions of artworks and other models. The options range from the simple clay, wax and alginate to sophisticated materials like polyurethanes, latex rubber, silicone rubber, thermoset mold rubber and so on.

Each material comes with its own set of advantages and disadvantages. The choice will depend on various considerations that includes the material of the model, the choice of casting material and even the personal preference of the mold maker, to name a few.

Yet, it emerges that polyurethane mold rubber and silicone mold rubber are usually preferred by mold makers owing to different factors like the versatility of the materials, the inherent ease of use and also the durability of the molds.

So, let’s take a look at how an artist would choose between polyurethane rubber and silicone rubber to understand how these factors play out in reality:
  • Polyurethane mold rubber is a popular option for casting wax, plaster and especially concrete. Concrete casts are usually made in polyurethane rubber molds only as silicone may cause efflorescence in the castings. Silicone rubber is preferred when the artist has to go on to cast polyester, epoxy and polyurethane resins. In other words, silicone rubber is usually used for making a resin casting.
  • Generally, both polyurethane and silicone rubbers can be used on any model of any material without causing any damage. However, if the artist is making a body mold from a live human being, they have to use special skin safe silicone rubber only.
  • While the mold rubber itself will not damage an inanimate model, the release agent can definitely have an adverse effect on the surface. Therefore, in case the artist cannot or does not want to use a release agent, silicone rubber will be the material of choice since it does not stick to anything except itself. However, it follows that silicone rubber molds cannot be used for making silicone rubber casts!
  • Polyurethane rubbers are more economical than the highly expensive silicone mold rubbers. It is obvious that an artist will prefer the polyurethane variant whenever it is suitable.
  • The final choice will also be influenced by the dexterity of the artist. Many artists prefer to use a particular mold making material just because of the familiarity and comfort level with the same.

It is possible to play around with these factors depending on the circumstances too. For instance, polyurethane rubber molds can be used for making hundreds of plaster, wax and concrete molds while silicone molds are suitable for large quantity of resin castings without any distortions or damage. However, in case the artist requires only 10 to 20 resin cast parts, they may opt for polyurethane rubber molds since it is easier on the pocket. But using a release agent will become mandatory!

Sealing Mold Box Is Essential

Posted by EnvironMolds , Labels: , , , , Tuesday, July 9, 2019 2:47 AM

Some mold makers skip sealing the mold box thinking that even if the mold making material tends to leak from the edges, they can always clean the mess later. But can you really afford to do so? Find out why….

One of the first steps for making a mold is making a mold box. This is a structure that is used to contain the model. For making a small rubber or resin casting, a cup, bowl or bottle can easily serve as the mold box. However, it is essential that the ‘box’ should be able to contain the entire model. That’s not all – it should also allow sufficient space around and over the edges of the model so that the mold making material can form a thick rim around the model.

Mold makers often use different materials to make the mold box – think cardboard, plastic, acrylic sheets, wood, metal or even lego blocks to form the containment field. Ready-to-use mold boxes are also available in art stores and these can be adjusted to suit the dimensions of the model.



Irrespective of the type of mold box, it is essential to seal and caulk the mold box properly. Else, consider this - leaving a mold box with a leak to cure overnight is likely to result in a half-complete mold in the morning!

So, isn’t it better to create a waterproof seal around the edges of the mold box? Applying glue or clay around the exterior perimeter and up the corners of the box will seal the edges and keep the runniest of mold making materials from leaking out of the mold box. Plasticina clay is considered best for this purpose.

Another important step is to apply a release agent inside the mold box and glue the base of the model to the bottom of the box. This will ensure that the model does not shift while the mold making material is poured into the box. Demolding will be easy as well.

All materials like clays, polyurethanes and rubbers along with supplies can be easily sourced from EnvironMolds at https://www.artmolds.com

Why You Need A Secondary Mold?

Posted by EnvironMolds , Labels: , , , , Monday, April 30, 2018 11:19 PM

A mold that accurately reproduces the shape and details of a model can be used for rubber or resin casting, as needed. In fact, depending on the type of mold and the casting process used, a mold can be used over and over to make multiple casts of the same object.

casting resin types



However, every mold comes with a finite use life. It may end up deformed, tarnished or even cracked and broken after repetitive use. Would you then go back to making a mold of the object all over again? In case of a life cast, does it make sense to go to the trouble of making a body mold again and again? 

Anticipating such scenarios, experienced mold makers prefer to make a secondary mold before starting the casting itself. This copy can be used to continue with the casting even when the original one is spoiled or damaged. Moreover, it is possible to vary the material for making the secondary mold – like choosing polyurethanes or rubbers - thus extending the life of temporary alginate molds and the like.



Secondary molds bring another benefit into play. If the original mold has minor faults like bubbles, wrinkles or spots, the secondary mold opens up the possibility of correcting the flaws by improvising on the original piece. In fact, a mold maker can make one secondary mold after another till all the defects are corrected and the mold becomes perfect in every sense.

Therefore, mold makers are always advised to make a secondary mold just to be on the safe side at least.

Be Familiar With The Types Of Casting Resins

Posted by EnvironMolds , Labels: , , , , Monday, February 5, 2018 9:21 PM

The desire of man to do something innovative as well as eye-catching is the main reason behind the invention. It is not the story of the era. From centuries ago, people have developed several things to make their life comfortable and the process is continuing still today.



Molding and casting are the processes with which one can let his or her imagination run free. Resin casting is one among them. It is a method of plastic casting where a mold is generally filled with synthetic resin that later hardens.

Casting resin falls into three classes epoxy, polyester and polyurethane. Polyester resin is used for its mechanical properties. It is a contact product that requires no pressure to cure as well as can be cured from a fluid or solid state. The two varieties of polyurethane resins are opaque and water clear resin. Epoxy resin is more expansive than other types. It might take several hours to several days to completely cure.

Of Reusable Mold Making Materials

Posted by EnvironMolds , Labels: , , Wednesday, August 24, 2016 11:52 PM

Regular mold making materials such as clay, alginate, plaster bandages, silicone rubber and polyurethane rubber are good for single use. In other words, you can use them to make a mold once and that is it. While clay, silicone or polyurethane molds can be used multiple times, the material itself cannot be used again to form a new mold.

Perhaps the only reusable mold making material is thermoset mold rubber!

Thermoset mold rubber comes in a box and has to be heated (in a microwave) until it melts completely. Now the molten rubber is directly poured into the mold box to completely cover the model. That’s it, no measuring or mixing is required. It gradually hardens on cooling, and soon a flexible rubber mold is ready for use.

The mold made can be repeatedly used to produce multiple casts without any noticeable degradation whatsoever. And once you are finally done using the thermoset rubber mold, it can easily be melted and reused to make new molds quite effectively. In fact, some thermoset mold rubbers such as Wizbe’s Composi-Mold can be re-melted and reused as many as 35 times!

Three variants of Composi-Mold are available at EnvironMolds website artmolds.com
  • Composi-Mold-LT - a soft flexible rubber which sets similar to a Shore A 10.
  • Composi-Mold-PowerMold - a firmer version for making two part or push molds with Shore A 25 hardness.
  • ComposiMold-FC - a FDA compliant food grade mold rubber.
In sum, thermoset mold rubber is an extremely cost-effective option over the regular polyurethanes for sure!

Water Glass Works as an Effective Deflocculant too!

Posted by EnvironMolds , Labels: , , , Monday, March 16, 2015 5:24 AM

I always thought that water glass or sodium silicate is mainly used for making sand mold castings and getting an antique finish on ceramics. I had vaguely heard that it works as a high temperature adhesive too, but was not aware of its binding and sealing properties.

However, it was only when I started working on clay slips for ‘gluing’ my clay pieces together, that I came to know that the same sodium silicate is the most powerful, economical and commonly used deflocculant for clay.

Sodium silicate will work to thin the clay or reduce its viscosity by dispersing its particles. This allows the slip to be produced with minimum water so that drying shrinkage can be curtailed as much as possible. This may sound hazy, but the simple effect is that sodium silicate works like magic! You have to see it to believe it.

However, you need to keep in mind that after a point sodium silicate starts having an opposite effect, i.e., it actually makes the clay thicker or flocculates it. This is why you need a precise formulation of clay, water and water glass, with the latter never exceeding0.5% of the entire formulation.

If you are wondering where to source this clay slip deflocculant, just turn to EnvironMolds. This leading manufacturer and supplier of all kinds of mold making and casting products and equipment also offers the versatile ArtMolds Liquid Sodium Silicate to suit different applications.
