  A new transesterification catalyst comprises an epoxide and a non-acidic nucleophilic onium salt. Coating compositions having hydroxyl functional resin components and carboxylic ester components adapted for curing by transesterification following application to a substrate are formulated with in-situ formed cure catalyst comprising a non-acidic nucleophile and an epoxide-to-product coatings that readily cure by transesterification. Such coatings include polyesters, polyepoxides, and polyacrylates are useful in formulating high solids coating and powder coatings having exceptional physical properties. Extremely low-temperature cure coatings were obtained by transesterifying mixtures of polyols and polymeric esters having multiple activated ester linkages having the structure wherein Rʹ is lower alkyl and Y is -OH and O-alkyl radicals. These coatings provide low-temperature cure coatings for paper, plastic, and wood in addition to metal substrates. Such catalysts can be used in powder coatings compositions which comprise a hydroxyl functional binder having carboxylic ester functionality. Such resins include hydroxyl functional acrylic, hydroxyl functional polyester, ester functional polyesters and methyl succinate esters of bis phenol epoxides.

  The present invention provides one-component compositions which comprise one or more hydroxyl functional acrylic resin having a glass transition temperature (Tg) of from -100°C to -10°C and one or more dialkyl dicarboxylic acid ester endcapped polyisocyanate crosslinker, such as the isocyanurate of isophorone diisocyanate (IPDI), and flexible, environmental etch resistant coatings made therefrom. The acrylic resins comprise the polymerized reaction product of one or more flexibility conferring monomers, e.g. butyl acrylate, and provide the coating with its flexibility. The one or more dialkyl dicarboxylic acid ester endcapped polyisocyanate and the hydroxyl groups in the one or more acrylic resins react to cure at lower temperatures than current one-component blocked isocyanate coatings. Alternatively, one-component coating compositions consists essentially of one or more rigid hydroxyl functional acrylic resin and one or more dialkyl dicarboxylic acid ester endcapped aliphatic polyisocyanates. The present invention provides coated, environmental etch resistant exterior automotive plastic parts, such as bumpers, fascia, body trim and body molding.
