EZ-Spray® Silicone 20 and 22
are sprayable platinum-cure silicones that cure quickly to soft rubbers with high elongation and tear strength. Liquid silicone is sprayed through the EZ-Spray® Junior Cartridge System or SilCon® III Meter Mix and Spray Machine.
After a suitable thickness is attained, EZ-Spray® Silicone 20 cures in about 20 minutes
while EZ-Spray® Silicone 22 cures in about 45 minutes
. EZ-Spray® Silicone cures with negligible shrinkage to strong, durable and flexible finish suitable for production casting of polyester, epoxy or urethane resins, gypsum, concrete and other materials. EZ-Spray® Silicone 20 and 22 silicones are effective for making reusable cost-effective vacuum bags fast for producing composite parts.
Newly fabricated vacuum bags can be removed from the tool assembly in a matter of minutes and be put into production service immediately.
