Abstract
Aqueous-based release coating compositions are disclosed. The disclosed aqueous-based release coating compositions are particularly suitable for use with pressure sensitive adhesives. In some embodiments, the aqueous-based release coating compositions include (A) a vinyl-based emulsion copolymer comprising a copolymerizable acid monomer, (B) a silicone-based emulsion comprising a mixture of amine-, polyol-functional siloxane and epoxy-, glycol-functional siloxane, and (C) a polymeric dispersant comprising an acid functional group. In some embodiments, the weight ratio of silicone-based emulsion (B) to polymeric dispersant (C) in the aqueous-based release coating compositions is from 2:1 to 3:1. The disclosed release coating compositions are suitable for use in, inter alia, tape applications.
