GI-300 series RTV silicone rubbers are two-component, tin-catalyzed systems that cure at room temperature. They are versatile products that are excellent for electrical potting and
encapsulation. They can also be used for prototype or production molds to cast polyester, polyurethane or epoxy parts where flexing is not required. They are low viscosity compounds with a variety of hardnesses. The GI-300 series rubbers are not sensitive to inhibition, meaning they will cure at room temperature over virtually any surface. The speed at which the rubbers harden can be accelerated with special activators. The GI-300 series rubbers are especially useful in those applications where outstanding heat resistance and chemical resistance are required.
