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.

EZ-Spray® Silicone 35

EZ~Spray® 35 is a platinum cure silicone rubber developed specifically for spraying through the EZ~Spray® Junior Cartridge System. With no or minimal surface preparation, EZ~Spray® 35 can be sprayed onto vertical surfaces for making fast rubber molds of large surface areas. After a suitable thickness is attained, EZ~Spray® 35 cures in 1 hour with negligible shrinkage to a durable mold rubber good for production casting resins, foams, concrete, plaster and other materials. Application of a support shell is achieved by spraying Smooth-On’s EZ~Spray® Plastic over the rubber mold after it has fully cured. Read the EZ~Spray® Junior manual prior to spraying.
