A coating composition, particularly a clearcoat composition, which may be a two-component clearcoat composition, comprises a film-forming material, a crosslinking agent, and a nonlinear polysiloxane polymer having a functional group reactive with the crosslinking agent. The coating composition exhibits excellent scratch resistance and adhesion of repair coating layers and sealants, such as windshield sealants.

Nonlinear polysiloxane containing coatings with improved adhesion properties

Coating composition comprising (a) radiation curable component that polymerizes upon exposure to actinic radiation comprising at least two functional groups comprising at least one bond that is activatable upon exposure to actinic radiation, optionally, at least one isocyanate-reactive functional group, and optionally, at least one hydroxyl-reactive functional group; (a) thermally curable binder component that polymerizes upon exposure to heat comprising at least two functional groups that are reactive with functional groups of component (a), wherein at least 5% by weight based on a nonvolatile weight of component (a) is component (X) that is a polymer with at least two functional groups (a), a Tg of less than 0&#xb0; C., and an equivalent weight of greater than 225; (a) thermally curable crosslinking component comprising at least two functional groups that are reactive with functional groups of (a); and (a) optionally, at least one reactive diluent.

Dual radiation/thermal cured coating composition

A basecoat composition includes an acrylic polymer prepared from a combination of monomers including at least about 30% by weight ethyl acrylate, methyl acrylate, methyl methacrylate, or a combination of these. The basecoat composition also includes methylated melamine-formaldehyde resin and up to about 10% by weight of a butylated melamine-formaldehyde resin, based on the weight of the basecoat composition vehicle and butylated melamine resin. An at least partially cured layer of the basecoat composition offers improved adhesion with a coating composition layer applied over it and cured, whether the coating composition layer applied over it is another layer of the basecoat composition itself or a layer of a clearcoat composition.

Basecoat composition with improved repair properties

A coating composition comprising stabilized inorganic pigments is provided. The coating comprises a pigment treated with a pigment treatment composition of a polyester havng an acid number between 15 and 50 or a phosphate ester or pyrophosphate ester, having an acid number between 10 and 50, solvent, and an amino functional resin.

Coating composition comprising stabilized inorganic pigments

A method for stabilizing inorganic pigments in aqueous media and waterborne coating compositions is provided. The method comprises forming a pigment treatment composition of a polyester havng an acid number between 15 mg KOH/g and 50 mg KOH/g or a phosphate ester or pyrophosphate ester, having an acid number between 10 mg KOH/g and 50 mg KOH/g, solvent, and an amino functional resin. The composition is then deposited on the pigment. The treated pigment is stable in an aqueous environment and is suitable for waterborne coating compositions.

Stabilization of inorganic pigments in aqueous media

This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to water-dispersible polyurethane resins having polyether sidechains which may be utilized in basecoat compositions as principal resins or grind resins. These polyurethane resins may be laterally stabilized or terminally stabilized. The terminally stabilized resins of this invention are preferably employed as principal resins in basecoat compositions.

Novel non-ionic polyurethane resins having polyether backbones in

This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to the discovery that incorporating a long-chain carboxylic acid of at least 50% by weight of the carboxylic acid component used to make polyester resins which are further incorporated into polyurethane resins provides basecoat composition exhibiting low temperature flash characteristics. These low temperature flash characteristics are exhibited even where the basecoat is deposited at 50-90% relative humidity.

Polyurethane resins in water-dilutable basecoats having low flash and
