Abstract: A polyurethane reaction system includes an isocyanate component having at least one polyisocyanate and an isocyanate-reactive component having a storage stable polyol component that is a single phase liquid mixture at 23° C. including a first polyether polyol and a second polyether polyol. The first polyether polyol is included in an amount from 20 wt % to 90 wt %, based on total weight of the polyol component, is a glycol based polyoxypropylene-polyoxyethylene polyether polyol having number average molecular weight from 1500 g/mol to 1975 g/mol, and has a polyoxyethylene content from 26 wt % and 34 wt % based on a total weight of the first polyether polyol. The second polyether polyol is included in an amount from 10 wt % to 80 wt %, based on total weight of the polyol component, has a number average molecular weight from 750 g/mol to 4000 g/mol, and has a melting point higher than 23° C.

Abstract: A process comprising a) mixing i) an isocyanate reactive component that contains from 2 to 100 weight percent of an aminobenzoate terminated composition wherein the isocyanate reactive component does not contain a solvent; and ii) an isocyanate terminated component having an isocyanate functionality of from 2 to 6 wherein the isocyanate terminated component does not contain a solvent; at a stoichiometric ratio of NCO to reactive hydrogen in the range of from 0.9 to 2.5; to form an adhesive composition; b) applying the adhesive composition to a primary substrate; and c) laminating the primary substrate with a secondary film to form a laminate structure, is disclosed. The laminate structure can be used as a laminating adhesive.
