ABSTRACT:
An aqueous reaction mixture having a pH of 4.5 to 5.5 of a methyl terminated siloxane emulsified polymer, a methyl triethoxysilane, a mixture of nonyl and octyl phenol derivative surfactants, fluorinated alkyl ester surfactant and synthetic ethoxylated amine surfactants, a silanol terminated polydimethylsiloxane hydroxyl terminated polybutadiene and ethanol. The reaction mixture is coated on a mold core surface and cured with heat to form a mold release surface that can be used in excess of twelve times prior to recoating.
