An adhesive composition is provided. The adhesive composition for zipper bag application, comprising the following components: (a) a mixture of a polyurethane dispersion with acrylic emulsion, wherein the polyurethane dispersion comprises a reaction product of by dry weight based on total dry weight of the polyurethane dispersion, from 30% to 50% of a monomeric diisocyanate, from 45% to 69% of a polymeric polyol and from 1% to 15% of ionic surfactant, the polyurethane dispersion has a Tg of −15° C. to 15° C., and the acrylic emulsion has a Tg of −10° C. to 25° C., and wherein the ratio by weight of the polyurethane dispersion and the acrylic emulsion is from 15:85 to 85:15, (b) a polyisocyanate.

Adhesive composition

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.

Aqueous-based release coating compositions

The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.
