Abstract: Provided herein is a one-component polyurethane adhesive composition showing excellent adhesive strength on glass surfaces.

Abstract: In one aspect the invention is a composition comprising a prepolymer which is the reaction product of di(isocyanatophenyl) methane or a polymeric di(isocyanatophenyl) methane having an isocyanato functionality of about 2.1 to about 3.0 with a mixture of one or more diols and one or more triols wherein the ratio of isocyanate equivalents to hydroxyl equivalents in the reaction mixtures used to prepare the prepolymer is from about 1.2 to about 1.8 and the ratio of diol to triol where the diisocyanate is a di(isocyanatophenyl) methane in the reaction mixture is from about 5:1 to about 1:1. and where the isocyanate is a polymeric di(isocyanatophenyl) methane is from about 8:1 to about 4:1; wherein the prepolymer could further react with an isocyanate reactive monofunctional compound. The prepolymer herein has an isocyanate content of about 0.5 to about 1.5 percent by weight, a free isocyanate monomer content of about 1.0 percent by weight or less as measured by high pressure liquid chromatography.

Abstract: The invention is a composition comprising: a) one or more film forming resins having at least one functional group capable of polymerization; b) one or more reactive diluents capable of reacting with the film forming resin; c) one or more silicon, titanium, zirconium, aluminum or metal containing compounds capable of promoting adhesion of the composition to glass; d) one or more fillers capable of imparting abrasion resistance to the composition when cured; and e) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety. The composition of the invention is useful as a frit on the window of a vehicle. Furthermore, the invention relates to a method for applying the coatings to glass and a method for bonding the coated glass to a structure or substrate, for instance, a building.
