A coating composition is disclosed comprising a film-forming resin and a catalyst component. The catalyst component comprises a catalyst contained within or encapsulated by a carrier; at least some of the catalyst is capable of being released from the carrier via diffusion through the carrier and into the coating composition. Methods of controlling the rate of cure of a curable film-forming composition and increasing the pot life of the composition by adding such catalyst components are also disclosed.

Curable film-forming composition comprising catalyst associated with a carrier

Disclosed is a method of producing metal oxides, comprising electrodepositing a metal oxide from an electrolyte solution onto a substrate to coat at least a portion of the substrate, whereby metal oxide seed particles are released into the solution, and precipitating metal oxide particles from the solution. The precipitated metal oxide particles have a maximum particle size of less than 1 micron.

Electrolytic production of metal oxides

The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate combinations of curable film-forming compositions. The curable film-forming compositions may comprise functional film-forming polymers and curing agents or any of various polysiloxanes and optionally silanes with reactive groups. The film-forming compositions can be applied directly to the surface of the substrate or to a primer coat on the substrate.

Method of mitigating ice build-up on a substrate

The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate applying to the substrate a curable film-forming composition comprising: The film-forming compositions can be applied directly to the surface of the substrate or onto a primer coat on the substrate.

The present invention is directed to a coating composition comprising a polymer that comprises an oligomeric macromonomer and a core from which the oligomeric macromonomer extends, wherein the oligomeric macromonomer comprises reactive functional groups and has an average functionality ranging from 1.0 to 30, and wherein the core is &#x3c;10 weight % of the total polymer weight.

Coating compositions comprising a polymer containing an oligomeric macromonomer

Thermosetting compositions comprising an adhesion-promoting agent are disclosed. The adhesion-promoting agent is derived from boric acid or an equivalent and an ester having two or more functional groups that are derived at least in part from a 1,3-polyol.

Multi-layer composites formed from compositions having improved adhesion

A coating composition is provided comprising (a) a polymer containing reactive functional groups; (b) a curing agent having reactive functional groups that are reactive with the functional groups in the polymer in (a); and (c) a polymeric material different from (a) and (b) having functional groups. The functional groups in components (a) and (b) are more reactive with each other than with the functional groups in component (c) such that upon curing, at least a portion of the functional groups on component (c) remain unreacted. A coating layer formed from the composition upon application to a substrate has surface regions and a bulk region, and the concentration of component (c) at one or more surface regions is greater than the concentration of component (c) in the bulk region of the coating layer. The composition can be used in multi-layer composites containing two or more coating layers.
