    摘要: Ungelled polyester oligomers which are formed from reacting polyols, 1,2-dicarboxylic acid anhydrides and polyepoxides are disclosed. The polyesters are useful as resinous binders in high solids coating compositions. The coating compositions can be applied by spraying and do not result in a tacky overspray common with many high solids coating compositions.

    摘要: Ungelled hydroxyl-containing oligomers and their method of preparation are disclosed. The oligomers can be prepared by reacting an organic isocyanate with a half-ester formed from reacting a polyol with a 1,2-dicarboxylic acid anhydride followed by reaction with an epoxide. The oligomers are useful as resinous binders in high solids coating compositions. The coating compositions can be applied by spraying and do not result in a tacky overspray common with many high solids coating compositions.

    摘要: Resinous compositions useful as coating compositions comprise blends of hydroxyfunctional polymers; organoalkoxy silane crosslinking agents represented by the formula: R.sub.n Si(OR').sub.4-n wherein R is an aryl, alkaryl, aralkyl, alkyl having 1 to 8 carbon atoms, XR .sub.4 -- or ##STR1## RADICAL, WHEREIN R.sub.1 is hydrogen or an alkyl radical of 1 to 6 carbon atoms, R.sub.2 is a member selected from the group consisting of alkylene radicals of 1 to 7 carbon atoms and carbonyloxy radicals represented by the formula: ##STR2## wherein R.sub.3 is an alkylene radical of 1 to 6 carbon atoms, wherein R.sub.4 is an alkylene radical of 1 to 6 carbon atoms, a cycloalkylene radical, or an arylene radical and X is a functional group selected from the group consisting of --OH, --SH, ##STR3## halogen, NH.sub.2 --, ##STR4## and NH.sub.2 --CH.sub.2 --CH.sub.2 --NH--, and wherein R' is methyl, ethyl, 2-methoxyethoxy, 2-ethoxyethoxy, m is 0 or 1 and n is 0, 1 or 2; and cure accelerating catalysts. Hydroxyfunctional polymers such as hydroxyfunctional acrylic polymers, polyesters and polyurethanes are particularly useful. Organic acids, metallic salts of organic acids and organic bases are useful cure accelerating catalysts.
