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.
Mold Max™ 20
Mold Max™ Silicones are tin-cured silicone rubber compounds that have exceptional working properties and library life. Mold Max™ Silicones feature Smooth-On’s exclusive “Libra™” catalyst for long library life. Mold Max™ silicones can be pigmented with Silc Pig™ silicone colorants. Pot life for the pourable silicones is 45 minutes and they cure overnight at room temperature.
Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.
