RTV-2 GI-1120 - SOLIAO

About
GI-1120 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for casting polyester parts. GI-1120 is especially good for molds with deep undercuts and for molds that require flexing for part removal. GI-1120 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 beaccelerated 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-1120 is extremely useful for those applications where superior elongation and medium durometer are required.&&
