EZ~Spray® Silicone 20 & 22
EZ~Spray® Silicone 20 and 22 are platinum-cure silicones that cure
quickly to a soft rubber with high elongation and tear strength. They
can be sprayed through the EZ~Spray® Jr. System and other spray
systems. They cure with negligible shrinkage to strong, durable
mold rubbers good for production casting of polyester, epoxy
or urethane resins, gypsum, concrete and other materials.
EZ~Spray® Silicone 20 and 22 are ideal for making fast, reusable
vacuum bags for producing composite parts.
Perfect for Vacuum Bagging & Resin Infusion! 4
