A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.

A coating composition is provided that is useful in coating metal substrates such as interior and/or exterior surfaces of food or beverage cans. In preferred embodiments, the coating composition is formulated using a physical blend of a preformed_resin system and an alkali-soluble resin additive.

A tannin-blocking coating is provided. The coating includes a binder resin and casein proteins. The tannin-blocking coating mitigates migration of tannins from a substrate on which the tannin-blocking coating is placed.

A multi-part water-borne coating composition is provided. The multi-part composition includes water, a first part, and a second part. The first part comprises (a1) a core-shell latex copolymer having pendant hydroxyl and pendant carbonyl groups. The second part comprises (b1) at least one polyisocyanate compound having pendant NCO groups. The multi-part composition also includes at least one polyhydrazide compound having at least two hydrazide groups of the formula C(O)NHN(R.sup.h)(R.sup.i), wherein R.sup.h and R.sup.i are independently H or C.sub.1-C.sub.12 alkyl. The molar ratio of hydroxyl groups to NCO groups in the composition is from 5:1 to 1:5. The molar ratio of hydrazide groups to carbonyl groups in the composition is from 5:1 to 1:5.

Coating systems, composite articles formed from the coating systems, and methods of forming the composite articles are provided herein. In an embodiment, a coating system comprises a waterborne underlying composition comprising an acrylic latex resin and a two-part waterborne clearcoat composition. The two-part waterborne clearcoat composition comprises a clearcoat binder part and a clearcoat crosslinker part. The clearcoat binder part comprises a water-dilutable, hydroxyl-functional (meth)acrylate copolymer. The clearcoat crosslinker part comprises a polyisocyanate compound having pendant NCO groups. A cured film of the waterborne clearcoat composition having a film thickness of 67.5 m overlying a cured film of the waterborne underlying composition having a film thickness of 20 m disposed on a substrate exhibits a popping density of less than about 3 pops per square centimeter, as measured by visual observation with the naked eye at a distance of 30 cm under a fluorescent light source.
