Patent ID: 7754812

Claim:
A hot melt adhesive or pressure sensitive adhesive comprising an admixture of at least one adhesive material and at least one adhesion promoter, wherein the adhesion promoter comprises a silane composition comprising a hydrolytic silane compound in an aqueous buffer solution including a buffer agent, wherein the buffer agent is an alkali metal phosphate, an alkali metal sulfite or mixture thereof, and wherein a ratio of the hydrolytic silane compound to water in the aqueous buffer solution prior to admixture with the at least one adhesive material is within the range from 1:0.05 to 1:0.5 by weight, and wherein a ratio of the hydrolytic silane compound to the buffer agent in the aqueous buffer solution prior to admixture with the at least one adhesive material is within the range from 1:0.005 to 1:0.25 by weight.
