Disclosed herein are a more efficient method for manufacturing paints and a universal extender pigment grind that can be used for the paints in the same paint line as well as in different paint lines, while producing paints with similar properties as paints manufactured under traditional manufacturing techniques. The universal extender pigment grind comprises a minimum amount of diatomaceous earth.

Manufacturing method for multi paint finishes and a multi-finish extender grind

Disclosed herein are methods for pasteurizing architectural coating compositions using heat, radiation or other energy sources without additionally polymerizing the compositions and storing same.

Pasteurizing paints and method for pasteurizing paints

Disclosed herein is a polymeric paint additive that increases the open time and the flow and leveling of paint compositions, as well as, maintaining/improving paint film properties such as scrub resistance, water sensitivity, surfactant leaching and stain removal. The polymeric open time additive preferably has a high glass transition temperature, e.g., above 100&#xb0; C., as determined by the well-known Fox's equation, and molecular weight of less than 20,000 Daltons (number average molecular weight). The particle size of the inventive polymeric open time additive is in the range of about 130 nm to about 230 nm (volume average), prior to being dissolved in a basic solution, such as an aqueous architectural composition.

Acrylic-peg open time additive

Disclosed herein is a method for adjusting factory-made tintable paints at the point of sale by adding at least one gloss modifier to the factory-made tintable paints without substantially changing the amount of opacifying pigments in the tintable paints, so that a single color prescription can be used to tint the paints to a single color for any gloss or sheen. Such same color paints should have a color difference of less than 2.0 CIEDE2000 units. Also disclosed is an aqueous gloss reducer that contains mostly a matting agent with substantially no latex resin and substantially no opacifying pigments.

Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. For example, the water-borne composition may comprise polymers incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. The cross-linking functionality does not react with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of reacting with the alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.

Aqueous cross-linking compositions and methods

The present invention relates to a hybrid latex composition containing polymer particles that are polymerized in at least two stages including a first phase acrylic core polymer, and a second phase vinyl acrylic shell polymer including a monomer that is crosslinkable under ambient conditions. Paint compositions and architectural coatings containing the latex composition according to the invention are also described herein, as well as methods for making the same.

Sequentially polymerized hybrid latex

The present invention relates to self-coalescing latexes that incorporate film fat ing polymers that are low molecular weight polymers that are compatible with the latex and act as thin plasticizers penetrating through the remainder of the latex particle and aiding in the coalescence of the remaining polymers. In a preferred embodiment, the self-coalescing latex is a sequentially polymerized polymer having at least a core, a shell and a skin. The film forming polymers are formed of monomers substantially the same as the monomers of the shell but having average weighted molecular weights substantially less than the polymers of the shell. The present invention also relates to the method of polymerizing the self-coalescing latex of the current invention, which largely results from the addition of a substantial amount of chain transfer agent to a remaining portion, about 15% or less, of the monomer pre-emulsion prior to polymerization. Lastly, the invention relates to paint compositions incorporating the self-coalescing latexes that are substantially free of coalescing agents or aids.

Self-coalescing latex

The present invention is directed to a coating composition comprising a vinyl acrylic copolymer latex wherein said copolymer latex has a water contact angle of about 60&#xb0; or higher on the dried latex film surface, wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr. The invention is also directed to the copolymer latex itself. Further, the invention is a method of improving a coating's ability to withstand a high humidity environment comprising adding a vinyl acrylic copolymer latex to the coating composition wherein said copolymer latex has a water contact angle of about 60&#xb0; or higher on the dried latex film surface, and wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr.

Coatings for use in high humidity conditions

The present invention relates to substrates and coating compositions disposed thereon containing improved ultraviolet degradation resistance. Specifically, these coating compositions can contain multiple UV protectants and can advantageously be used in transparent, semi-transparent, and/or translucent coatings on substrates, particularly opaque or semi-opaque substrates such as wood, e.g., in order to inhibit, to reduce, and/or to minimize UV degradation of said substrates.

Translucent coating compositions providing improved UV degradation resistance

The present invention relates to polymers polymerized sequentially or in stages and having multimodal molecular weight distributions. The polymers according to the invention can advantageously be present in aqueous emulsion or latex form and can advantageously be used in paint compositions and other coating applications.

Emulsion polymers having multimodal molecular weight distributions

The present invention relates to polymers polymerized sequentially or in stages and having varied functionality and/or monomer content as the polymerization progresses, as well as the methods for making these polymers. The polymers according to the invention can advantageously be present in aqueous emulsion or latex form and can advantageously be used in paint compositions.
