Described are one-component, curable coating compositions that include (a) a polymer having a plurality of alkoxysilane groups; (b) a polyepoxide having a plurality of epoxide groups connected to a compound, oligomer, or polymer through ester linkages, ether linkages, or a combination of ester linkages and ether linkages; (c) a chelated metal alkoxide, in which the metal is aluminum, titanium, or zirconium, or a mixture of such chelated metal alkoxides; and (d) a monofunctional di- or trialkoxysilane compound, which may be volatile, with the proviso that the coating compositions are free of, or essentially free of, polymers with hydroxyl groups, primary amine groups, and secondary amine groups (i.e., amine groups with at least one active hydrogen, &#x3e;N&#x2014;H). These one-component, curable coating compositions do not require any additional ingredients to be mixed in before application, are storage stable with do not build viscosity during use (in other words, in use the pot-life is not shortened by crosslinking of internal components) so that excess material can be reused, yet the coating composition provides ambient cure when applied in a coating layer and exposed to moisture (i.e., atmospheric water vapor).

One-component, curable coating compositions, processes for making and using them, and coatings and articles prepared with them

A coating system comprises a substrate and a cured film disposed on the substrate and formed from a coating composition. The coating composition comprises a solvent component and a resin. The resin comprises a reaction product of a polyolefin and an oligomer or polymer. The polyolefin, different from the oligomer or polymer, has a functional group that is reactive with the oligomer or polymer and the functional group is selected from acrylate, methacrylate, carboxyl, hydroxyl, epoxide, anhydride and isocyanate functional groups. The oligomer or polymer and the polyolefin are at least partially immiscible in solution at ambient temperature. The oligomer or polymer is grafted with the polyolefin to form the resin.

Resin for use in a coating composition

Scratch resistance and/or reflow of a refinish topcoat is improved by preparing the topcoat from a refinish topcoat coating composition comprising an unsaturated fatty acid ester polyol that does not undergo oxidative cure when the applied refinish topcoat coating composition is cured.

Scratch resistant refinish clearcoat

An adhesion promoting composition includes a polymer, such as an acrylic copolymer, having acetoacetoxy functionality and adhesion-promoting functionality and a metal alkoxide, chelate, and/or alkoxide chelate. The composition is applied in a first layer over a metal substrate or a coated substrate, then coated with a desired refinish coating composition.

Adhesion promoting composition and method

Reactive diluents are formed by reaction of a compound having at least two glycidyl ester groups and a compound having at least one hydroxyl and/or carboxyl group. The diluents are useful in coating compositions together with crosslinking agents and optional other vehicle components.

Novel reactive carbodiimide compounds and their method of preparation are disclosed. These reactive carbodiimide compounds are especially useful in automotive paint compositions and more particularly in low volatile organic content (VOC) automotive paint compositions.

Reactive carbodimide compositions

The invention relates to a reduced temperature coating composition which dries to form films exhibiting desirable properties comprises a blend of (1) a principle film forming resin with reactive functional groups, typically hydroxyl, and (2) a fully alkylated, low imino aminoplast.
