Abstract:
The invention provides curable coating compositions comprising an aqueous dispersion comprising a stabilizing resin (P1) and a compound (P2) comprising functional groups reactable with a crosslinking agent. Compound (P2) is dispersed into stabilizing resin (P1). The coating compositions of the invention may further comprise an optional crosslinking agent (P3) which may or may not be dispersed into stabilizing resin (P1). In a particularly preferred embodiment, both the stabilizing resin (P1) and compound (P2) will comprise functional groups which are carbamate or are convertible to carbamate.
Abstract:
The invention provides carbamate-functional resins and coating compositions incorporating said resins that have improved adhesion with respect to subsequently applied films or coatings. More particularly, the invention relates to carbamate-functional addition polymers having at least 250 grams of polymer per carbamate group which are made with less than 35 percent by weight of nonfunctional monomers, preferably with less than 20 percent by weight and most preferably from 0 to less than 10 percent by weight, based on the total weight of the polymer. The invention further provides a method of making a carbamate-functional polymer and carbamate-functional polymers made by the claimed method. Finally, the invention provides a method for improving the adhesion of a first coating composition to a subsequently applied material as well as a method of making a composite comprising a coated substrate, an adhesive composition, and a glass having at least one surface.
