Patent number: 9994722Abstract: 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.Type: GrantFiled: September 25, 2015Date of Patent: June 12, 2018Assignee: Columbia Insurance CompanyInventors: Robert J.

Publication number: 20180030237Abstract: 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.Type: ApplicationFiled: October 9, 2017Publication date: February 1, 2018Inventors: Yong Yang, Mohammed Asif, Robert J.

Patent number: 9790374Abstract: 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.Type: GrantFiled: June 3, 2011Date of Patent: October 17, 2017Assignee: Columbia Insurance CompanyInventors: Yue Chen, Yong Yang, Robert J.

Patent number: 9499680Abstract: 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.Type: GrantFiled: September 18, 2012Date of Patent: November 22, 2016Assignee: Columbia Insurance CompanyInventors: Shi-Jun Yang, Gary Dandreaux, Robert J.
