  • Publication number: 20210024794
    Abstract: The disclosed adhesive compositions comprise (A) an isocyanate component comprising an isocyanate-terminated prepolymer that is the reaction product of a polyisocyanate and an isocyanate-reactive mixture comprising a phosphate ester polyol. The disclosed adhesive compositions further comprise (B) an isocyanate-reactive component polyol component comprising a polyol. In some embodiments, methods for preparing two-component adhesives formulations are disclosed comprising preparing an isocyanate component comprising an isocyanate-terminated prepolymer by reacting a polyisocyanate with an isocyanate-reactive mixture comprising a phosphate ester polyol and preparing an isocyanate-reactive component comprising a polyol. The methods further comprise mixing the isocyanate component and the isocyanate-reactive component at a stoichiometric ratio (NCO/OH) of from about 1.0 to about 5.0. Methods for forming laminate structures, and the laminate structures themselves, are also disclosed.
