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

A siloxane-modified latex binder includes a polymerization product of a monomer or a mixture of monomers for producing a latex polymer and a non-hydrolyzable siloxane. The non-hydrolyzable siloxane is represented by Formula (I): wherein: R, R, R, R, R, R, R, and Rare independently hydrogen, alkyl, &#x2014;O-alkyl, &#x2014;OH, &#x2014;S-alkyl, &#x2014;SH, amino, amido, epoxy, carboxyl, acrylate, (meth)acrylate, cycloalkyl, aryl, alkalyl, polyether, alkenyl, or alkynyl; and n is an integer from 0 to about 300; provided that at least one of R, R, R, R, R, R, R, and Ris an alkenyl or alkynyl.

Siloxane-modified binders and compositions thereof

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

The present invention is directed to an aqueous architectural composition comprising a low Tg (less than about &#x2212;10&#xb0; C. and higher than about &#x2212;50&#xb0; C.) acrylic emulsion polymer with at least one cross-linkable moiety, and solid polyutherane (PU) or polybutylacrylate microspheres having a mean weight diameter of less than about 40 microns and a Tg of less than about 0&#xb0; C., wherein the solid PU spheres make up about 10% to about 20% by weight of the composition. The solid acrylic polymer without water and the PU spheres make up about 30% to about 40% by weight of the aqueous composition. A dried paint film formed by the inventive aqueous architectural composition can withstand at least about 500 cycles on the scrub test, and a gloss value at 60&#xb0; of less than about 2.5 GU.

Aqueous paint compositions with soft feel and light diffusion effects

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.

Reduced point of sale bases for multi-finish paint line and methods for same

The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.

Environmentally friendly colorant compositions and latex paints/coatings

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 relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2% of HEC by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mV) latex particle size is in the range of about 320-about 850 nm. Paint compositions incorporating the HEC grafted acrylic latex show high viscosity at static conditions and have no color flow and no syneresis compared paints containing a latex without HEC grafting. The present invention also relates to a cross-linking mechanism that cross-links latex particles at ambient conditions. This cross-linking mechanism comprises diacetone acrylamide (DAAM) and methacrylamide (MAM) with or without styrene.

Hydroxyethyl cellulose grafted acrylic latex

The architectural compositions, such as paints and stains, include an additive comprising a plurality of latex particles added to an existing mixture of opacifying pigments and a film-forming binder as an admixture. Each latex particle is made from a latex polymer copolymerized with a polymerizable surfactant. The latex polymer is a non-film forming polymer at ambient temperatures.

Additives for improved hiding and paint compositions containing same

The present invention relates to storage stable film forming latex particles that crosslink under ambient conditions during or after drying. Monomers for the formation of the crosslinkable moieties in the latex particles include diacetone acrylamide (DAAM) or the likes and methacrylamide (MAM) or the likes with or without styrene. A paint composition comprising the storage stable latex particles that may include a small amount or crosslinking agent such as adipic acid dihydrazide (ADH) in the aqueous phase is also described.

Ambient self-crosslinkable latex

The present invention relates to storage stable film forming latex particles substantially free of adipic acid dihydrazide (ADH) that crosslink under ambient conditions during or after drying. Monomers for the formation of the crosslinkable moieties in the latex particles include diacetone acrylamide (DAAM) or the likes and methacrylamide (MAM) or the likes with or without styrene. A paint composition comprising the storage stable latex particles was described.
