Product Description
EpoxAcast™ 650 BLACK + 102 Hardener
EpoxAcast™ 650 Black is a mineral filled general purpose casting epoxy that is low cost and versatile. It features a low mixed viscosity for minimal bubble entrapment.
Free Form™ Habitat™ Black
Free Form™ Habitat™ Black Epoxy Putty is a mix-by-hand putty that is used to create textured or highly detailed display pieces. Habitat™ Black is solvent-free and contains no VOC’s. Working time is 60 minutes and cure time is 16 hours at room temperature (73°F/23°C). Epoxy cures to a very hard, heat resistant material that is easily painted.
Use with Habitat™ Black Folding Powder – fold powder into epoxy putty to thicken and reduce sag when applied to a vertical surface. Folding Powder™ also reduces stickiness and makes the epoxy more handle-able.
