Abstract:
A two-component solventless adhesive composition is disclosed, the composition comprising an isocyanate component comprising an isocyanate prepolymer that is the reaction product of reactants comprising at least one polyisocyanate, at least one polyester polyol, at least one polyether polyol, and at least one polyol comprising a hydroxyl and COOH acid functionality. The adhesive composition further comprises a polyol component comprising at least one polyester polyol, at least one polyether polyol, or a combination thereof. A method for forming a laminate using the adhesive composition and a laminate itself are also disclosed. The method comprises forming a solventless adhesive composition, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. A laminate made according to the method is further disclosed.
