<p>Non-fluorinated epoxy resins 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 thus obtained, having a fluorine content of not higher than 15% by weight and, preferably, ranging from 1% to 5%, based on the total weight, exhibit a variety of properties which are typical of the corresponding fluorinated resins having a much higher fluorine content, in particular, oil and water repellence, resistance to hydrolysis and to solvents and minimum absorption of water.</p> |
