Abstract : The patent describes highly fluorinated ester-anhydrides and diacids which are formed by reacting an acid anhydride chloride or a diacid with a perfluorinated aliphatic alcohol. The fluorinated esters will cure epoxy resins and form plastics which exhibit a low degree of wettability, a low degree of surface friction, and a low degree of water absorption. The fluoroester-cured epoxy resin plastics are useful in sonar dome and hydrofoil coatings, molded plastic articles, fuel tank linings, and aircraft adhesives.
