Abstract: A composition for and method for bonding a substrate. In general, applied to a substrate will be a primer composition that includes an adhesion promoter, which is an adduct prepared by the reaction of at least one aromatic polyisocyanate compound, with an active hydrogen containing moiety of an organofunctional silane, and a prepolymer derived from the reaction of at least one aliphatic polyisocyanate and a polyol, and is at least partially reacted with an active hydrogen containing moiety of an organofunctional silane.

Abstract: The invention is a composition comprising a) one or more prepolymers having on average three or more aliphatic isocyanate groups and further containing alkoxysilane groups; b) one or more aromatic polyisocyanates; c) one or more compounds having at least one heterocyclic ring which hydrolyzes when exposed to moisture to form at least one isocyanate reactive group; d) one or more solvents; and e) one or more amine and/or organometallic polyurethane catalysts; wherein the ratio of aromatic isocyanate groups to aliphatic isocyanate groups in the composition is from about 0.5:1.0 to about 1.5:1.0, preferably about 0.9:1.0 to about 1.5:1.0, and the equivalent ratio of isocyanate groups to isocyanate reactive groups derivable from the one or more compounds having at least one hydrolyzable heterocylic ring is from about 0.8:1.0 to about 5.3:1.0, and most preferably about 1.5:1.0 to about 1.7:1.0.
