Product Description

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. It is also used for industrial bonding applications. 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.

Habitat™ Flex FR forms a permanent bond to a variety of surfaces including foam, steel and stainless steel, wood, PVC, ABS plastic, concrete and more. It withstands freeze/thaw cycles for exterior applications. When using as an adhesive do not use folding powder. It is easy to paint with acrylic paints or stains. Use to make perfectly detailed tree branches, planks and other themed elements for zoos and amusement parks. Because finished elements are semirigid, reptiles and birds can comfortably grip them without affecting the material.

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.
