An aqueous reaction mixture having a pH of 4.5 to 5.5 of a multi-functional polydimethyl siloxane emulsified polymer, a methyl triethoxy silane, a mixture of substituted nonyl and octyl phenol derivative surfactants, non-ionic fluorinated alkyl ester surfactant and synthetic ethoxylated amine surfac
An aqueous reaction mixture having a pH of 4.5 to 5.5 of a multi-functional polydimethyl siloxane emulsified polymer, a methyl triethoxy silane, a mixture of substituted nonyl and octyl phenol derivative surfactants, non-ionic fluorinated alkyl ester surfactant and synthetic ethoxylated amine surfactants, a silanol terminated polydimethyl siloxane 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 twenty times prior to recoating.
