Create detailed rubber shapes that are ready to use in fifteen minutes or less. Unlike traditional casting compounds, which can take up to 24 hours to set, these compounds harden after two minutes, and can be removed from molds within fifteen. Use them to make your own prototypes, molds, and linings.

Combine acrylic or silicone with a 69° cure temperature compounds in different ratios to adjust the consistency from thin to thick. Thin mixtures are easier to pour and better for filling small crevices. Thick mixtures will shrink less as they dry.

Silicone with a 70° cure temperature compounds are a putty that you can mix with your hands and form into any shape. Press an object into these compounds to create a mold for casting duplicates. They do not shrink as they dry, so textures and other fine details are captured faithfully. Soft silicone is more flexible and easier to peel off of molds than firm silicone, especially when making complex shapes.Firm silicone holds its shape better than soft silicone, so small ridges and channels are less likely to collapse or deform while making molds.

Compounds with dispenser gun come ready to use—no mixing required—and won’t leave a mess.

Create transparent molds to monitor fill levels, differentiate parts at a glance, and avoid damaging parts when cutting the mold away. These casting compounds are two parts that activate when mixed.

Urethane compounds create hard molds, which are good for delicate and intricate shapes because the small contours won't deform or collapse when the material is poured in. Although not required, curing urethane molds inside a vacuum chamber improves their clarity. By removing trapped air bubbles, the chamber prevents the finished mold from looking speckled.

Silicone compounds handle higher temperatures than urethane compounds—up to 570° F. Silicone also cures faster than urethane, and it won't shrink as it cures, which means you won't need to guess at the final size of your mold. Because silicone compounds trap air bubbles when mixed, they must be cured inside a vacuum chamber. The chamber removes the trapped air bubbles, strengthens the mold, and improves its clarity.

Create rubber molds that retain their shape for decades—they won’t soften, degrade, or warp, so you can continue to replicate intricate parts. Because these compounds don’t shrink as they cure, they are more accurate and predictable than other compounds.

Create lightweight molds with these two-part compounds. They expand as foam after they’re poured to fill every cavity. The denser the foam, the less it will expand. Before casting, apply petroleum jelly (not included) to prevent sticking, stretching, and tearing. It won't cause the foam to collapse as it cures.

Flexible compounds cure into soft, open-cell foam, which absorbs water, air, and gases. They are often used to cast gaskets, cushions, and other bendable objects.

Rigid compounds form stiff, closed-cell foam, which prevents water and air from flowing through the part. Machinable, they’re dense enough to create prototype modeling blocks, so you can test setups without wearing down tools.

Apply this liquid for a skin-tight protective coating that insulates and resists moisture, acids, and corrosion. It adheres to metal, plastic, vinyl, rubber, and composite surfaces.

Liquid rubber is moisture and crack resistant. Use it as a seal on plastic tape. Allow 20 minutes between coats.

Liquid vinyl is for use on electrical connections and terminals.

Liquid that cannot be sold outside the United States is restricted by product labeling requirements.

Fill cracks with these coatings to stop leaks and deaden sound. They resist rust, salt, and acid. Coatings that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).
