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.

Abstract: Provided herein is a water-based hybrid pressure sensitive adhesive composition and a method of producing the same. The composition comprises: (A) 100 parts by mass of a silicone pressure sensitive adhesive; (B) 5 to 80 parts by mass of an acrylic pressure sensitive adhesive; (C) water in a sufficient amount to emulsify or disperse components (A) and (B) in component (C); and (D) 0.1 to 10 parts by mass of an amino-functional alkoxysilane compound, a hydrolysate thereof, or a hydrolyzed condensate thereof. Components (A) and (B) are emulsified or dispersed in component (C). The composition can be cured to form a pressure sensitive adhesive exhibiting good peel adhesion and low silicone migration.

Abstract: An aqueous dispersion of a silicone pressure sensitive adhesive base can be combined with a curing agent and cured to form a silicone pressure sensitive adhesive. The aqueous dispersion of the silicone pressure sensitive adhesive base includes a bis-hydroxyl-terminated polydiorganosiloxane; a polyorganosilicate resin; cumene; a surfactant; and water. A curing agent such as a peroxide compound or an aminosilane may be combined with the aqueous disperison of the silicone pressure sensitive adhesive base to form a silicone pressure sensitive adhesive composition. A pressure sensitive adhesive article may be formed by a method including coating a surface of a substrate with the silicone pressure sensitive adhesive composition, removing water, and curing the silicon pressure sensitive adhesive composition to form a silicone pressure sensitive adhesive on the surface of the substrate.
