A coating composition is disclosed, comprising a binder component having hydroxyl-functional groups; a curing agent having functional groups, wherein the functional groups of the curing agent are reactive with the hydroxyl-functional groups of the binder component; and pulverized rubber, the pulverized rubber having particles with a size suitable for spraying the coating.

Automotive coatings comprising pulverized rubber

A coating composition is prepared by polymerizing an addition polymer with a Tof at least about 60&#xb0; C. in the presence of a particulate pigment having substantially primary aggregate particles to form encapsulated pigment particles, isolating and drying the encapsulated pigment product, and combining the dried encapsulated pigment product with a coating vehicle.

Method to incorporate pigment into paint by formation of resin beads

A coating composition comprises at least one material dispersed in a vinyl or acrylic polymer, wherein the vinyl or acrylic polymer comprises (a) one or more anchor group monomer units (a) having an ionizable or active hydrogen functionality or a functionality that forms a covalent bond with the dispersed material, wherein the ionizable functionality is other than a carboxylic acid group in which the carbonyl carbon is separated from the closest ethylenically unsaturated carbon by at least four atoms and the anchor group monomer units (a) are other than those having polyoxyalkylene groups; (b) about 5% to about 45% by weight of one or more stabilizer monomer units (b) having a carboxylic acid group in which the carbonyl carbon is separated from the closest ethylenically unsaturated carbon by at least four atoms, having polyoxyalkylene groups, having gamma-hydroxy carbamate or beta-hydroxy carbamate groups, and combinations thereof; and (c) up to about 50 percent by weight of aromatic monomer units.

Pigment dispersant, method of making coating compositions, and coating compositions

A coating composition comprises at least one pigment dispersed in an acrylic polymer, wherein the acrylic polymer is prepared by first polymerizing a mixture of ethylenically unsaturated monomers comprising:

The present invention is directed to a pigment dispersant composition for use with inorganic pigments in coating compositions. The dispersant composition includes a vinyl or acrylic copolymer and a transition metal or rare earth metal salt. The metal salt in combination with the copolymer is useful with inorganic pigment as it lowers the viscosity of the pigment dispersions, thus allowing a higher concentration of pigment in the dispersion and consequently providing dispersions with higher non-volatile content and higher pigment to binder ratios. The presence of the metal salts in the dispersant composition when used with surface coated metal flake pigment provides excellent corrosion reduction of the metal pigment, indicated by the reduction or elimination of hydrogen gassing by the pigment in a coating composition.

Waterborne basecoat with copolymer dispersant composition for inorganic

The present invention is directed to a process for the preparation of modified copolymers as a pigment dispersant for coating compositions comprising the steps of

Process for the preparation of a modified copolymer as a pigment

Copolymer dispersant composition for inorganic pigments

The present invention is directed to a pigment dispersant for use in coating compositions. The dispersant is the reaction product of a functionalized copolymer, a polyalkylene glycol monoalkyl compound to impart water soluble character to the copolymer, and a compound having a pigment interactive substituent including hydrazine derivatives and oxime containing compounds.

Polymeric pigment dispersants for use in coating compositions

The present invention is directed to a pigment dispersant for use in coating compositions. The dispersant is the reaction product of a functionalized copolymer, a polyalkylene glycol monalkyl compound to impart water soluble character to the copolymer, and a urea-containing pigment interactive substituent that enhances pigment dispersion in solution.
