Product Description

EZ-Spray® Silicone 22

EZ~Spray® Silicone 22 are sprayable silicones which cure quickly to soft rubbers with high elongation and tear strength. Liquid silicone is sprayed through the EZ~Spray® Junior Cartridge System which is an economical alternative to expensive spray equipment. After a suitable thickness is attained, EZ~Spray® Silicone 22 cures in about 45 minutes. EZ~Spray® Silicone cures with negligible shrinkage to strong, durable silicone rubbers good for production casting of polyester, epoxy or urethane resins, gypsum, concrete and other materials.

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).
