Abstract: A curable epoxidized polyester-based composition useful for powder coatings application is provided by epoxidizing a polyester having a melting point of at least 90.degree. C. and a viscosity of at most 50 Poise@ 200.degree. C., where such polyester is a polyester prepared by reacting (I) a tetrahydrophthalic acid or anhydride, (ii) at least one cycloaliphatic polyol, (iii) at least one saturated polycarboxylic acid, and (iv) optionally at least one other alcohol under conditions effective to obtain a solid polyester having a melting point of at least 90.degree. C. Curable coating powder is obtained containing the epoxidized polyester and a solid carboxylic acid curing agent having an acid equivalent weight within the range of from about 100 to about 1500.

Abstract: A stable aqueous emulsions of epoxy resins are provided using an epoxy-functional polyether having the formula: ##STR1## wherein R.sup.1 is a C.sub.1 -C.sub.15 alkyl, aryl or alkylaryl group, R.sup.2 is a divalent aliphatic group, a divalent cycloaliphatic group, a divalent aryl group, or a divalent arylaliphatic group, R.sup.3 is independently a hydrogen or a C.sub.1 -C.sub.10 alkyl group, R.sup.8 is a divalent aliphatic group optionally containing ether or ester group(s) or together with R.sup.9 or R.sup.10 form a spiro ring optionally containing heteroatoms, and R.sup.9 and R.sup.10 are independently hydrogen or R.sup.9 or R.sup.10 together with R.sup.
