CURABLE EPOXY BASED COMPOSITIONS HAVING REDUCED SHRINKAGE DURING CURE

A curable composition is composed of (a) one or more epoxide group containing materials containing at least two epoxide groups per molecule; (b) a positive amount of an effectively thermoplastic polyester which does not exceed 40 percent by weight based on the total weight of the epoxide and polyest...

Beschreibung
Zusammenfassung:	A curable composition is composed of (a) one or more epoxide group containing materials containing at least two epoxide groups per molecule; (b) a positive amount of an effectively thermoplastic polyester which does not exceed 40 percent by weight based on the total weight of the epoxide and polyester components of the composition, said polyester having a weight average molecular weight of less than 10,000 and being insoluble in the one or more epoxide group containing materials of (a); and (c) a curing agent adapted to cure the one or more epoxide group containing materials of (a). m
