发明名称 CROSSLINKING OF EPOXYRESINS BY MEANS OF POLYFUNCTIONAL PERFLUORO-POLYETHERS
摘要 Non-fluorinated epoxy resins of known type are crosslinked by means of polyfunctional perfluoropolyethers containing groups which are reactive with the epoxy groups and/or with the hydroxy groups present in the starting resin. The thus-obtained crosslinked products having a fluorine content of not more than 20% by weight, preferably from 5% to 15%, are endowed with a set of properties typical of the corresponding fluorinated resins with a much higher fluorine content, in particular, water- and oil-repellence, resistance to hydrolysis and to solvents, minimum water absorption.
