Abstract:
An aqueous composition comprising polymer particles of one or more multistage aqueous emulsion, at least one of which is a multistage aqueous emulsion copolymer comprising polymerized units derived from monomer X in at least one stage, wherein monomer X is selected from polymerizable derivatives of imidazole, imidazoline, amidine, pyridine, pyrrole, pyrrolidine, pyrrolidinone, caprolactam, and combinations thereof. Also disclosed are methods of making and using the compositions.

Abstract:
Adhesion between a coating and a substrate may be improved by pre-treating the surface of the substrate with an aqueous detergent composition having a pH above 8 and comprising from 1 to 10 % by weight phosphate and from 1 to 10 % by weight silicate, before application of the coating.

Abstract:
Use of a coating comprising an acid-functional polymer formed from 0.1% to 20% by weight, based on the total weight of said polymer, of at least one acid-functional monomer and from 0.1% to 20% by weight, based on the weight of said acid-functional polymer, of at least one organosilane having a number average molecular weight of from 100 to 10,000 as at least one of the following: a tannin stain block, a scrub resistant, a water whitening resistant, a hot block resistant, a fire and smoke block, a nicotine stain block, a pen and ink stain block, water stain block and an adhesive improver.
Abstract:
A latex binder suitable for producing high gloss coating on weathered substrates and a method for producing such coatings. The binder includes a low molecular weight and low acid number latex polymer having an acid functional and an enamine functional moiety that results from the reaction of ammonia or amine with an acetoacetyl functional pendant moiety on the latex polymer. A film containing the latex binder is applied on a substrate and then exposed to ambient light and air to produce a high gloss highly adherent film on difficult to adhere surfaces, such as weathered chalky substrates.
