Abstract:
In one embodiment the invention is An adhesive composition comprising a) a polymer having a flexible backbone and a reactive moiety capable of cross-linking, b) a particle comprising an active agent encapsulated in an encapsulating agent wherein the active agent comprises a catalyst for cross-linking of the reactive moiety, a curing agent for the reactive moiety, an accelerator for the curing reaction or a mixture thereof; and the encapsulating agent comprises a side chain crystallizable polymer wherein the active agent is not substantially extractable from the particle at ambient conditions in a first extraction after particle formation.

This composition is used in binding two subtracters together.
Abstract:
In one aspect, the present invention is a method for treatment of a painted or glass surface so as to provide improved adhesion of a urethane adhesive applied thereafter, comprising the steps of applying a pre-wipe solution to the surface, the pre-wipe solution comprising an a hydrocarbyl substituted aromatic sulfonic acid and a solvent for the acid which is soluble in the solvent; and allowing the solvent to evaporate. In a second aspect, the present invention is a pre-wipe composition comprising from about 0.5 percent to about 10.0 percent by weight of the acid and from about 90.0 percent to about 99.5 percent by weight of solvent for the acid.
