Product Description
Ecoflex™ 5
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
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.
