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.

Smooth-Sil™ 960

Smooth-Sil™ 960 is a Shore 60A platinum cure silicone rubber developed for a variety of industrial applications. Compared to other 60A platinum silicones, Smooth-Sil™ 960 has a relatively low viscosity and is easy to mix, de-air and pour. Silicone cures in 16 hours with negligible shrinkage to a firm rubber with high tensile and tear strength.

Smooth-Sil™ 960 offers good chemical and heat resistance, making this a good choice for production casting of resins and expanding foams. Because of its firmness, Smooth-Sil™ 960 molds are also used for spin casting. It is also used for embedding and electrical applications. Smooth-Sil™ 960 is suitable for food related applications. 
Note: This product will not cure against surfaces containing sulfur, even when sealed.
