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™ Fire Safe™
Free Form™ Habitat™ Fire Safe™ epoxy putty is a high density epoxy sculpting putty that is flame rated (E84, Class A). Habitat™ Fire Safe™ is solvent-free and contains no VOC’s. Working time is 90 minutes and cure time is 16 hours at room temperature (73° F/23° C). Epoxy cures to a very hard, flame and heat resistant material that is easily painted. Habitat™ Fire Safe™ does not contain any carcinogens (cancer causing agents).
