ABSTRACT:
A two component polyurethane adhesive and a method of bonding construction materials to various construction substrates. The adhesive being the reaction product of two separate components that are mixed together immediately prior to application upon dispensing onto a substrate. The first part of the adhesive, referred to as the "A-side" is a polyisocyanate prepolymer, preferably a polymeric MDI (methylene diphenyl diisocyanate) based prepolymer. The second part of the adhesive, referred to as the "B-side" is a blend of elastomeric and flexible polyglycols. The adhesive formed by mixing the A-side and B-side components, is a frothing foam that has a consistency such that it does not run or drip when applied to the substrate, that expands upon application to the substrate surface to fill voids or imperfections, that collapses when the material to be bonded is placed in contact with the adhesive, and that has a rapid cure time.
