ABSTRACT:
The present invention is directed to a method of imparting moisture resistance to epoxies. Moisture resistant epoxy compositions are formed from epoxies and alkenylsuccinic anhydride (ASA) such as tripropenylsuccinic anhydride (TSA). The epoxy compositions, following cure, show surprisingly improved moisture resistance and retention of properties when exposed to warm, humid environments.
