Abstract

A room temperature curable organopolysiloxane composition is provided which includes an organopolysiloxane, a curing agent, and a specific organic compound incorporating at least one sulfur atom within each molecule. By producing a molding matrix with this type of composition, unsatisfactory curing of an unsaturated polyester resin is unlikely to occur at the contact surface with the silicone rubber of the matrix, and furthermore the mold releasability of the matrix relative to unsaturated polyester resins is excellent. As a result, the matrix can be used repeatedly for a significant number of molding operations.
