Condensation Cure Mould Making Silicone:

Condensation cure mould making silicone is a kind of room temperature vulcanized mold making silicone rubber. Since its based on tin catalyst, its also known as tin cure 2 part rtv silicone rubber. Its part A is flowable liquid silicone, part B is the curing agent(Tin catalyst). Condensation cured silicone is mainly used for silicone mold making.

Applications:

This tin cure 2 part rtv silicone rubber is mainly used as mold making silicone to make silicone molds for casting concrete ,wax, gypsum, polymer modified gypsum, urethane, epoxyresin,polyester resins ,etc.
