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™ Styrocoat™

StyroCoat™ Plastic is a flame rated (E-84) sprayable polyurethane plastic formulated to economically coat a variety of surfaces. Dispensed through Smooth-On’s EZ~Spray™, Jr. cartridge system, the plastic cures in about 2 seconds and can be applied to vertical surfaces without running off. An advantage of the system is that large areas can be covered in a short period of time. Cured plastic is lightweight, flame, impact, and water resistant. It can be sanded for priming and painting. Plastic can also be sprayed into a rubber mold to make fast, impact resistant castings (application of a release agent may be necessary before spraying into the mold). StyroCoat™ Plastic is used for theme design / fabrication applications, making movie set environments, making surfaces water resistant and other industrial applications.
