GI-1110 5 Gallon Kit Special Order

GI-1110 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for
casting polyester parts. GI-1110 is especially good for molds with deep undercuts and for
molds that require flexing for part removal. GI-1110 is not sensitive to inhibition, meaning it will cure at room temperature over virtually any surface. It is easy to mix and de-air, and will cure with only a slight degree of shrinkage. The speed at which the rubber hardens can be
accelerated with special activators. Condensation cure two-component silicone rubbers are
excellent for most general mold making and prototype applications. They are excellent for
casting waxes, gypsum, epoxies and other plastics. GI-1110 is extremely useful for those
applications where superior elongation and low durometer are required.
