Product Description
Brush-On™ 50
Smooth-On’s Brush-On™ Series of mold rubbers are extremely versatile and are famous for their abrasion resistance and high tear strength. They have the convenience of a one-to-one mix ratio and are easy to mix and apply with a brush or spatula.
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.
