Abstract
Non-fluorinated epoxy resins of a known type are cross-linked by means of polyfunctional fluoroalkanes containing groups which are reactive with the epoxy groups and/or with the hydroxy groups present in the starting resin. The cross-linked products so obtained, having a fluorine content not higher than 15% by weight, and preferably ranging from 1% to 5%, exhibit a complex of properties which are typical of the corresponding fluorinated resins having a much higher fluorine content; in particular, oil- and water-repellency, resistance to hydrolysis and to solvents, and minimum absorption of water.
