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.
EZ-Spray™ Silicone 22
EZ~Spray™ Silicone 22 is a sprayable silicone which cure quickly to soft rubbers with high elongation and tear strength. 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.
