Abstract: Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1.4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1.5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.

Abstract: The use of an amine salt of trifluoromethanesulfonic acid as a catalyst for the curing of hydroxyl-functional resins provides a wrinkle finish. The hydroxy-function may be present in polyesters, epoxies, and acrylate or methacrylate resins, among others. The polyester resins which are able to provide such a finish have a hot plate melt flow of at least about 50 mm but if it is more than 150 mm, the gel time of the resin must not be more than about 280 seconds. The minimum gel time in the case of polyesters is about 30 seconds.

Abstract: A flexible, aminoplast-curable film-forming composition and a process for preparing multi-layered coated articles coated with a pigmented or colored base coat and a transparent or clear topcoat are disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a transparent topcoat to the base coat. The transparent topcoat composition is a flexible, curable film-forming composition comprising (1) a polyether polymer containing a plurality of terminal or pendant carbamate groups of the structure: ##STR1## and (2) an aminoplast crosslinking agent. The topcoat composition provides a flexible composite coating with improved acid etch resistance, making the composite coating particularly useful as a topcoat for plastic automotive parts.
