Two-component adhesive compositions and methods of making same

A method for forming a laminate, comprising:

• mixing reactants to form a solventless adhesive composition, the reactants comprising:
• an isocyanate component comprising an isocyanate prepolymer that is the reaction product of a polyisocyanate and an isocyanate reactive component comprising at least 40 wt % of a polyester polyol, based upon the dry weight of the isocyanate reactive component;
• a polyol component having an average functionality between 2.5 and 4.5 and an average molecular weight between 250 and 1,000, and comprising at least 30 wt % of a polyether polyol, based upon the dry weight of the polyol component;
• and
• an adhesion promoter;
• applying a layer of the adhesive composition to a surface of a first substrate;
• bringing the layer into contact with a surface of a second substrate to form a laminate;
• and
• curing the adhesive composition.
