Claims9
An epoxy ester composition comprising the reaction product of:
- (a) a diglycidyl ether of a dihydric phenol;
- (b) castor oil polyglycidyl ether;
- (c) a dihydric phenol;
- (d) a monocarboxylic fatty acid;
- and
- (e) a dimer acid,
- wherein the sum of the epoxide equivalents of (a) and (b) and the phenolic equivalents of (c) are in the ratio of about 2:1 to about 4:3;
- wherein about 70 to about 80 percent of the epoxide equivalents are derived from (a) and the remainder from (b);
- wherein (d) and (e) are present in the amount of about 26 to about 42 weight percent (e), said weight percents being based on the total weight of (a), (b), (c), (d) and (e).
