<p>The use of interlinked polymers for bobbin coating based on perfluoropolyether polymers that comprise repeated unit sequences of one or more oxyfluoroalkylenic units such as -CF2CF2O-, -CR4R5CF2CF2O- wherein R4 and R5 equal to or different to each other choose between H, Cl, F or perfluoroalkyl of one to four carbon atoms, -CF2CF(CF3)O-, CFYO- wherein Y is equal to F or CF3, having a hydroxylic bifunctional termination, the interlinking carried out with blocked polyisociantes that have at least three NCO groups.</p> |
