Condensation Cure RTV Silicone

Easy to use RTV silicone rubber have excellent release properties, which makes production casting of resins (polyurethane, polyester, and epoxy) quick and easy. No release agent is required for nearly all surfaces (although silicone will bond to itself) and for all resins poured into it. These silicones also exhibit good chemical resistance and high temperature resistance (over 200 °C). For this reason silicone molds are suitable for casting low melting point metals and alloys (e.g. zinc, tin, pewter).

Condensation cured silicones use a tin based catalyst system and are most popular for their ease of use and economy.
