Solventless Adhesive Composition

Abstract

A two-component solventless adhesive composition, including: (a) at least one isocyanate component comprising an isocyanate-terminated polymer; and (b) at least one isocyanate-reactive component being reactive with the at least one isocyanate component, component (a); wherein the at least one isocyanate-reactive component, component (b), comprises a material having at least two functional groups including: (b′) at least one first functional group; wherein the at least one first functional group is selected from the group consisting of: at least one phosphate ester functional group, at least one phosphonic acid functional group, and mixtures thereof; and (b″) at least one second functional group reactive with the at least one isocyanate component, component (a); wherein the least one second functional group is selected from the group consisting of: at least one hydroxyl functional group, at least one carboxylic acid functional group, and mixtures thereof; a method for forming a laminate structure using the above solventless adhesive composition; and a laminate structure formed using the above method.
