Reliable solutions for craftsman



SILASTOSIL® M line molding and mold-making silicone rubbers are two-component, room-temperature-vulcanizing RTV-2 silicone rubbers and ideal for reproduction of figurative sculptures. Original pieces are most often sculpted and carved from wax, clay or wood and a mold material is poured, brushed or sprayed for the reproduction. Our solutions are widely used by sculptors and foundries for wax, resins, plaster, concrete and lost wax process of bronze casting to make accurate reproductions of original sculpture. Reproductions also can be cast in urethane plastic, epoxy resin, plaster, and concrete.
