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.

EZ-Spray® Foam

EZ~Spray® Foam is a polyurethane foam compound that can be conveniently sprayed using Smooth-On’s EZ~Spray® Junior System. Foam cures quickly to strong, lightweight and impact resistant 8 lb. rigid foam that can be used for a variety of applications including making lightweight castings. Foam can also be sprayed over certain rubber mold configurations as a mother mold material. For more information, refer to SmoothOn’s EZ~Spray® Junior manual and video.

Ecoflex™ 00-50

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, or you can choose to mix and 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.
