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™ Flex FR

Free Form™ Habitat™ Flex FR Epoxy Putty is a mix-and-apply-by-hand putty that is that is certified flame resistant (E84, Class A) and is used to create display elements that are semi-rigid and extremely tough. Habitat™ Flex FR is solvent free and contains no VOC’s. Working time is 90 minutes and handling time is 24 hours at room temperature (73°F/23°C). Cured epoxy has some flexibility with excellent impact resistance and abrasion resistance.

Use with or without Habitat™ Folding Powder™ – mix equal parts A+B and apply Habitat™ Flex FR. For thickening, add Folding Powder™ into epoxy putty. Folding Powder™ reduces stickiness and makes the epoxy more handleable. Once putty is applied, it can be stamped with a silicone rubber stamp to create repeating patterns with intricate detail over a large surface area. Surface can be smoothed with alcohol or water. New Habitat™ Flex FR will bond to cured Habitat™ Flex FR without delamination.
