Abstract: The invention pertains to a method for bonding a first substrate to a second substrate, including the steps of (a) applying to one or both of the substrates 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 moiety of an organofunctional silane (e.g., an aminosilane, a mercapto-silane, or a combination thereof); (b) applying an adhesive to at least one of the substrates; and (c) assembling the two substrates. Another aspect of the invention the adhesion promoter is incorporated into a primer composition that includes a polymeric prepolymer with a free isocyanate content, and more specifically, at least one prepolymer (derived from the reaction of at least one aliphatic polyisocyanate and a polyol), which is at least partially reacted with an amino group of an aminosilane, wherein the aminosilane includes a plurality of alkoxy groups bound to silicon.

Abstract: A composition and method for bonding to a substrate. In general applied to a substantially transparent substrate will be a primer composition that includes a reaction product prepared by the reaction of at least one isocyanate including a thiophosphate with an amino-silane, a mercapto-silane, or a combination thereof.
