Polycondensation Tin KIT

Polycondensation silicones are two component, Room Temperature Vulcanizing (RTV-2) silicone rubbers that are historically known for classical mold making and are the highest level of development aiming at the longest resistance (mechanical/chemical) and low inhibition sensibility. These RTVs are catalyzed using tin salts and produce water during the curing process. Polycondensation silicones are economical, slower curing products that are well suited for architectural molding including plaster, gypsum, and concrete, as well as for other general-purpose applications.

Product properties may vary depending on the paired catalyst. See the technical data sheet for details.
