RTV 3481 Silastic is a market leading condensation cure silicone rubber that offers outstanding tear strength and high elasticity for easy demoulding of complex replica parts.

A thixotropic agent can be added to the silicone for vertical surface replication.

The resultant RTV-3481 silicone moulds can be used to produce cold castings from materials such as polyurethane resins (eg Easyflo), polyester resins (eg CK427PA), Jesmonite & Plaster of Paris.
