Abstract: A coating composition comprises at least one solvent, at least one resin, and at least one filler, wherein the filler is silica-deficient, sodium-potassium alumina silicate. The silica-deficient filler may be a sodium-potassium alumina silicate that contains less than 0.1 percent by weight crystalline silica and is 5 percent by weight or less of the coating composition or 1 percent by weight or less of the coating composition. In the later instance, the coating composition contains less than 0.001 percent crystalline silica. The resin may comprise styrene, styrenic copolymers, or mixtures including styrene. The composition provides a temporary gloss coating that may be removed physically, as by peeling for example. A method for coating a substrate with a coating that maybe removed by physical means is also provided. The method comprises applying the disclosed coating composition.
Abstract: A paint brush and method include a ferrule extending around and in contact with a plurality of bristles and a spacer apparatus positioned to space apart the plurality of bristles to provide at least one reservoir within the plurality of bristles. The spacer apparatus defines at least one opening extending through the spacer apparatus that allows fluid passage therethrough to the at least one reservoir to assist in removal of paint from the plurality of bristles when fluid is provided therein.

Abstract: Polycyclocarbonate compounds and upgraded molecular weight polymers made from such compounds are provided. The polymers have particular utility in coating compositions, especially for use on food and beverage contact substrates that are formed into or will be formed into containers or container components.
Abstract: The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.

Abstract: A coating system for application to metal components prior to assembly or fabrication into large metal objects is described. The system includes a composition comprising a water-dispersible polymer component, a crosslinking agent, and a conductive material. When applied to a metal substrate, the coating system is weldable and provides optimal corrosion resistance during fabrication or assembly.
Abstract: The present invention is directed to a coating composition or paint comprising a multistage latex with at least first and second stages, wherein the composition or paint is substantially free of volatile organic compounds (VOC) and capable of film formation even in the absence of coalescent agents. The base paint formulation is capable of being tinted at a point-of-sale (i.e. in-store) using a colorant composition of a type and quantity required to produce a paint of desired color and finish. The paints, show improved block resistance, scrub resistance and tack resistance. Rheological techniques as described herein may be used to determine tack resistance, print resistance, and other performance characteristics.
