A solvent borne coating composition comprising a resin, a polyether modified dimethylpolysiloxane, and parachlorobenzotrifluoride.

Coating containing adhesion promoting additive

The refinish compositions contain an acetoacetate resin based on a monomeric polyol or a hydroxy-functional oligomer of such a polyol; a blocked polyamine (polyketimine and/or polyaldimine), pigment, and alkyd polymer. The alkyd is not reactive toward the acetoacetate resin or the blocked polyamine. The refinish compositions may be prepared from an intermix system that has a plurality of color bases and an unpigmented component. Each color base includes the alkyd resin and one or more pigments dispersed with the alkyd resin. The unpigmented component includes at least one of the acetoacetate-functional resin or the blocked polyamine. A drier for the alkyd resin may be included in one of the components or in a separate, additional component.

Automotive refinish coatings with low volatile organic content

Disclosed is a carbamate-functional acrylic polymer having an epsilon-caprolactone moiety beta to a carbamate group and a coating composition containing the acrylic polymer of the invention. The coating composition is particularly useful as a refinish coating and in refinish coating methods.

Durable refinish coating

A polyurethane coating is prepared on a substrate using a multi-component coating composition having a first component containing a polyisocyanate material, a second component containing a polymeric polyol, and a third component containing a compound having at least two hindered secondary amine groups by first determining the temperature at curing of the coating will take place and then combining the first and second components and, when the cure temperature is less than about 20&deg; C., particularly less than about 10&deg; C., also combining the third component to prepare a combined coating composition; then applying the combined coating composition to the substrate and curing the applied coating layer.

Method and system for low temperature cure of automotive refinish coatings

Air-dry refinish primer compositions containing microparticles have been found to exhibit superior air-dry properties as well as being resistant to solvent attack when a primer-surfacer or topcoat is applied after a short (30 minute or less) dry time of the primer composition.
