Abstract (en)

[origin: WO9849215A1] 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 DEG C and a viscosity of at most 50 Poise@ 200 DEG 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 DEG 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 100 to 1500.
