Material Data For GE Silicone II

Member of Material Category: Thermoset Polymers


GE Silicone II is a 1-part, room-temperature vulcanizing (RTV) silicone household sealant/caulk/adhesive. It is available in several colors, including transparent, white, black, bronze, and beige. It is easily dispensed from a variety of taper tip diameters, tolerates high temperatures (~392F/200C), and is very chemically inert. It is tack free in ~ 1-2 hours per mm of thickness, and fully cured in 24 hours. When cured, it forms a semi-soft rubber material. It can also be used to make molds for other materials, including epoxies. Before casting epoxy into a silicone mold, be sure that it is fully cured, and coat it with a mold-release agent - for instance cooking spray, or a thin film of dish soap.
