Product Description

FlexFoam-iT!™ 15 Tuff Stuff SLOW

FlexFoam-iT!™ Series foams are premium quality water blown flexible foams that can be used for a variety of industrial, special effects and art & crafts and projects. With several to choose from, uses include making theatrical props (swords, knives, hammers, etc.), industrial gaskets, custom padding and cushioning, and more. FlexFoam-iT!™ foams are also used as repair materials for seats, cushions and archery targets. SO-Strong™, UVO™ or IGNITE™ colorants can be added for color effects.

Part A and B liquids are combined, mixed and poured into a mold or other form (apply release agent if necessary). Mixture will rise and cure quickly to a solid, flexible foam. Foams vary by density and offer good physical properties. The lower the number, the more the foam expands.

SORTA-Clear™ 40

SORTA-Clear™ Series rubbers are premium water clear translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. This product requires a gram scale for measuring parts A + B. SORTA-Clear™ 40 comes in Shore 40A hardness and features high tensile and tear strength.

SORTA-Clear™ silicones are ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can then be cast into SORTA-Clear™ silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA-Clear™. SORTA-Clear™ can be pigmented with SILC Pig™ silicone pigments.

SORTA Clear™ 40 silicone rubber is FOOD SAFE and can be used for culinary applications including casting chocolate and other confections.

Certified Skin Safe - Cured SORTA Clear™ 40 is skin safe and certified by an independent laboratory.
