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.

Econ® 60

Econ® 60 is an economical and fast curing Shore 60A urethane rubber. It has no odor, features a convenient 1A:1B by volume mix ratio and a low viscosity for easy mixing and pouring.  Working time is about 6 minutes and handling time is 4 hours at room temperature. Translucent clear amber color (light passes through) makes Econ® 60 easy to color with SO Strong®, UVO® or IGNITE® colorants.  Econ® 60 is used to make limited run production rubber molds, stamping pads, rubber prototype parts, rubber props and pour-in-place gaskets for industrial equipment. It is also suitable for coating fabrics.
