RTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type. In general, RTV-2 Silicone rubber is a two-component material, and the silicone rubber includes Part A base silicone and Part B CA30 curing agent. The Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction.

RTV2066&RTV2088 silicone rubber is especially suited for reproduction of middle size cement molds, concrete stones, and artificial stones. Etc...

Platinum cure silicones, also called addition cure silicones, are two-component high tear strength, flexible mold compounds. They are recommended as a mold material for casting polyurethane, epoxy, and polyester resins, wax and a wide range of other casting materials. They exhibit extremely low shrinkage and high physical properties. These rubbers are chemically sensitive to latex, sulfur, and certain other materials.
