Product Description
EpoxAcast™ 690
EpoxAcast™ 690 is an UV resistant clear casting epoxy resins suitable for a variety of industrial and art related projects requiring a rigid, clear finished casting. EpoxAcast™ 690 features a very low viscosity for easy mixing and minimal bubble entrapment. Castings cure with negligible shrinkage and are very hard and strong. Resin can be colored with UVO™ or IGNITE™ colorants. Cast Magic™ and Glow Worm™ powders can also be added to create amazing casting effects.
FlexFoam-iT!™ 17
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.
