Patent number: 10040966Abstract: The present invention is directed to an aqueous architectural composition comprising a low Tg (less than about ?10° C. and higher than about ?50° 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° 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° of less than about 2.5 GU.Type: GrantFiled: May 6, 2016Date of Patent: August 7, 2018Assignee: Columbia Insurance CompanyInventors: Yong Yang, Glenn Cooper, Robert Sheerin, Johanna Garcia, Clarena Shavel

Patent number: 9505922Abstract: 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.Type: GrantFiled: May 15, 2012Date of Patent: November 29, 2016Assignee: Columbia Insurance CompanyInventors: Hrire Gharapetian, Navin Tilara, Robert Sheerin

Patent number: 9040617Abstract: 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. The water-borne composition may comprise one or more polymers formulated from one or more monomers of which at least one is a monomer that yields acetaldehyde as a hydrolysis product, and incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. Neither the cross-linking functionality nor the acetaldehyde reacts with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of conversion to an 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: February 8, 2013Date of Patent: May 26, 2015Assignee: Columbia Insurance Company, Inc.Inventors: Yong Yang, Johanna L.

Patent number: 8815981Abstract: The present invention relates to a dispersion of hybrid organic-inorganic nanocomposite molecules comprising discrete inorganic silica nanoparticles that are covalently bonded to organic polymers, wherein the dispersion has a high solid content (>30% wt.) and high silica content (>35% wt.) with low coagulum (about 100-400 ppm or about 0.05% wt or less). The hybrid organic-inorganic nanocomposite is prepared by (1) hydrolyzing silane monomers at acidic conditions; (2) surface treating inorganic silica nanoparticles with silane monomers; (3) stabilizing the surface-treated inorganic silica nanoparticles with an amine stabilizer; and (4) reacting organic monomers with surface-treated inorganic silica nanoparticles.Type: GrantFiled: February 11, 2011Date of Patent: August 26, 2014Assignee: Columbia Insurance CompanyInventors: Yong Yang, Johanna Garcia de Visicaro, Robert Sheerin
