The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate curable film-forming compositions comprising isocyanate-functional curing agents, film-forming compositions with functional groups reactive with the isocyanates, acrylic polymers having polysiloxane side chains, and polysiloxanes.

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 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.

The present invention is directed to a method of mitigating ice build-up on a substrate, such as a wind blade, comprising applying to the substrate curable film-forming compositions comprising isocyanate-functional curing agents, film-forming compositions with functional groups reactive with the isocyanates, and polysiloxanes. The film-forming compositions can be applied directly to the surface of the substrate or onto a primer coat and/or topcoat on the substrate.

Coating compositions are disclosed comprising a polyester comprising at least two reactive hydroxyl groups, a material comprising at least two functional groups reactive with the hydroxyl groups of the polyester, and a free acid. Methods of using the coatings, methods for refinishing an article with the coatings, and the substrates coated therewith, are also disclosed.

Coating compositions that include a polyester polyol, related coated substrates, multi-layer coating and methods

Methods for coating articles that include a plastic substrate are disclosed. Certain methods include the steps of (i) applying a composition that includes an adhesion promoting agent to at least a portion of the substrate by a first application technique, (ii) applying a composition that includes an adhesion promoting agent over at least a portion of the composition applied in step (i) by a second application technique that is different from the first application technique, and (iii) applying a protective and decorative coating system over at least a portion of the compositions applied in steps (i) and (ii). Systems for coating articles that include a plastic substrate are also disclosed.

Methods and systems for coating articles having a plastic substrate

Coating compositions comprised of (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) tartaric acid, malic acid, adipic acid, succinic acid, or anhydrides of said acids; and an anhydride curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel and cold rolled steel without the use of a chrome containing wash primer.

Coating compositions with dicarboxylic half ester containing polymers and polyanhydride curing agents

Coating compositions comprising (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) citric acid or citric acid anhydride; and (b) an anhydride functional curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel substrates without the use of a chrome-containing wash primer.

Carboxyl-functional adduct from oh- or epoxy-functional polymer and

Coating compositions comprised of a film forming polymer which is the reaction product of (a) a compound containing pendant and/or terminal hydroxyl or epoxy functional groups and (b) citric acid or citric acid anhydride. The coating compositions have enhanced adhesion to galvanized and galvanealed steel substrates without the use of a chrome containing wash primer.

Coating compositions with citric acid containing polymers for enhanced

A coating composition and method for protecting anodized aluminum, and the coated product are disclosed, wherein the coating comprises a crosslinking agent; a film-forming resin selected from the group consisting of polyester polymers, thermosetting acrylic polymers, and mixtures thereof; and an epoxy silane. The combination provides exceptional adhesion of the coating to anodized surfaces as well as good hardness.

Anodized aluminum having protective coating

A laminated transparency with an electroconductive coating positioned within the laminate. An edge coating composition is applied about the periphery of the laminate to seal the edge of the coating and prevent coating degradation.

Windshield edge seal

A coating composition, containing a fluoropolymer, a film-forming adjuvant resin which is different from the fluoropolymer and adapted to react with the group represented by F in the functional organosilane of formula I and which is selected from the group consisting of acrylic resins, polyepoxide resins, polyester resins, aminoplast resins and mixtures thereof; and an amount effective to promote adhesion of a functional organosilane represented by formula I: ##STR1## wherein A represents an organo group containing from 1 to 18 carbon atoms,
