Patent ID: 8168019

Claim:
A method of bonding a glass panel to a vehicle structure, comprising the steps of (a) applying a primer composition including (a) an isocyanate functional prepolymer derived from the reaction of an aliphatic polyisocyanate and a polyol, and which is partially reacted with an amino group of a secondary aminosilane, wherein the aminosilane includes two or three methoxy group bound to silicon, two or three ethoxy groups bound to silicon, or a combination thereof; (b) an isocyanate functional prepolymer with an isocyanate content greater than about 1%, which is the reaction product of an aromitic polyisocyanate and a polyol of Mn>300; and (c) at least one solvent for the components (a) and (b); and an ingredient including an oxazolidine ring or derivative or analog thereof substantially along the periphery of one side of a glass panel, (b) superimposing on the primer composition a bead of an adhesive; and (c) installing the glass panel by contacting the adhesive with a vehicle structure defining an opening for receiving the glass panel.
