ABSTRACT:
Vinyl ester resins processed until low epoxy values are reached are storage stable for two weeks at 54.degree. C. (130.degree. F.). Adding a copper salt inhibitor also provides two weeks storage stability at 54.degree. C. (130.degree. F.). A synergistic effect is observed if both low epoxy values are reached and copper naphthenate inhibitor is used, extending shelf life stability to two months at 54.degree. C. (130.degree. F.).
