BLUESIL RTV 3325

BLUESIL RTV 3325 is a condensation-curing silicone rubber for molding and reproduction. After adding a tin catalyst, it cures at room temperature into a soft, rubber-elastic vulcanizate. It is suitable for series molds for plaster, wax, and synthetic resins such as epoxy, acrylic, or polyester, for example for decorative objects, statuettes, furniture components, building elements, and molds for the lost-wax casting process. The non-adhesive, highly elastic surface facilitates demolding, the fidelity of reproduction extends to the finest detail, and the demolding time can be controlled through the choice of catalyst (CATA 24H, 6H, and others).
