    Abstract: The invention is a system, or kit, comprising i) a stable solution or dispersion of a catalyst for the curing of a reactive adhesive system; and in a separate part ii) an uncured reactive adhesive system wherein the catalyst of part i) accelerates the cure of the reactive adhesive system. The reactive adhesive system can be a one or two-part system. In another embodiment, the invention is a method of bonding a reactive adhesive to a substrate comprising: a) contacting a catalyst for the curing of the reactive adhesive in a volatile solvent with the surface of the substrate to which the adhesive will be bonded; b) allowing the volatile solvent to volatilize away; c) contacting a reactive adhesive with the surface treated in step a) and d) allowing the adhesive to cure. This process is performed in the absence of a primer and a film forming agent.

    Abstract: The invention is a composition comprising a) one or more organotitanates having four ligands wherein the ligands are hydrocarbyl, optionally containing one or more functional groups having one or more heteroatoms selected from the 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 invention 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 functional prepolymer.

    Abstract: In one aspect, this invention is a primer which comprises a solution of: (a) a polyester resin of a carboxylic acid and a glycol; and (b) a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; in a volatile solvent, wherein the weight ratio of (a):(b) is in the range of from about 0.25:1.0 to 2.0:1.0. In a second aspect, this invention is a primer which comprises a solution of: (a) 5-18 weight percent of a polyester resin of a carboxylic acid and a glycol; and (b) 6-17 weight percent of a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; in a volatile solvent. It has been discovered that the primer of the invention advantageously provides improved adhesion characteristics of metal-to-glass bonding when used to prime paint-coated metal substrates before the application of a urethane adhesive, particularly when used with a "fast cure" adhesive comprised of an isocyanate-functional prepolymer and dimorpholinediethyl ether.
