备注说明 | GI-1032 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for making case molds for the china and ceramics industries. GI-1032 is also excellent for casting polyurethane foam parts when a slightly higher hardness is desired. GI-1032 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-650 is extremely useful for those applications where a medium durometer is required. |
