Polymer latex binders useful for preparing coating compositions containing low levels of, or which are substantially free of, volatile organic compounds (VOCs) such as volatile freeze-thaw additives are prepared by multistage emulsion polymerization, wherein one stage provides a copolymer having a relatively high glass transition temperature and containing an oxyalkylene-containing (meth)acrylate comonomer.

A system for dispensing texture material in a desired spray pattern that substantially matches an existing texture pattern on a target surface has a container assembly, an actuator assembly, and a concentrate comprising a solvent/carrier comprising water, wall texture material comprising at least one filler and a resin/binder, a first anti-corrosion material, where the first anti-corrosion material is a phosphate ester, and a second anti-corrosion material, where the second anti-corrosion material is sodium nitrite. At least one of the first and second anti-corrosion materials forms a film on the inner surface of the container assembly while the concentrate is stored within the container assembly. The film inhibits corrosion of the corrodible material forming at least part of the inner surface of the container assembly. The first and second anti-corrosion materials together comprise 0.125-7.00% by weight of the concentrate.

A process for the production of a multi-layer coating includes applying a coating layer from an aqueous pigmented coating composition A onto a substrate provided with an EDC primer and applying a base coat layer from an aqueous coating composition B overlying the coating layer. A clear coat layer is applied onto the base coat layer and the three coating layers are jointly bake-cured. The coating compositions A and B are different from each other and coating composition A comprises (i) binder solids, (ii) free polyisocyanate, (iii) a pigment content free of special effect pigments and comprising carbon black pigment and/or titanium dioxide pigment, and (iv) talcum filler.
