Silicone Mold Release Agent for Rubber
Silicone-based mold release agents for rubber molding are used to prevent adhesion between cured rubber compounds and metal mold surfaces, enabling clean part ejection and extending mold life. They are available as solvent-based sprays, water-based emulsions, and semi-permanent coatings to suit different molding processes including compression, transfer, and injection molding. Silicone mold releases are compatible with a wide range of rubber types and cure systems including sulfur-cured and peroxide-cured compounds.
