Product Description

Free Form™ AIR HT

Free Form™ AIR HT is a low density, lightweight epoxy putty that offers high temperature resistance to 300°F/149°C when cured at room temperature and 400°F/204°C when heat post cured. This is a low-odor, low shrinkage formula that is easy to use. Free Form™ AIR HT is mixed by hand with a 2A:1B by volume or weight mix ratio. It offers a long working time and cures overnight at room temperature to a hard, rigid epoxy that is very strong with modeling board-like properties. It can be sanded, shaped, drilled, tapped and CNC machined/routered.

FlexFoam-iT!™ 14

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. 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.
