SYSTEM FOR BONDING GLASS INTO A STRUCTURE

摘要

The invention is a composition comprising a) one or more organotitanates having four ligands wherein the ligands are hydrocarbyl, optionally containi ng one or more functional groups having one or more heteroatoms selected from t he group comprising oxygen, nitrogen, phosphorus and sulfur wherein two or more of the ligands may form a cyclic structure; b) one or more mercaptosilanes; c) one or more polyaminosilanes; d) one or more secondary aminosilanes; and e) a solvent which dissolves the components of the composition. This composition is referred to as a clear primer hereinafter. In another embodiment the inventi on is a system for bonding glass to a substrate which comprises a clear primer according to the invention; and an adhesive comprising an isocyanate functional prepolymer and a catalyst for the cure of the isocyanate function al prepolymer.
