Abstract
The present invention relates to new coating compositions for the preparation of functional surface coatings on various base material substrates. The coating compositions are based on a silazane-containing polymer and a fluorine-containing polymer, wherein the fluorine-containing polymer comprises a first repeating unit U1 and a second repeating unit U2. The coating compositions provide improved physical and chemical surface properties and may be applied by user-friendly methods.
Claims18
A coating composition, comprising:
- (i) a silazane-containing polymer;
- and
- (ii) a fluorine-containing polymer comprising a first repeating unit U1 and a second repeating unit U2;
- wherein the first repeating unit U1 is a fluorine-containing ethylene repeating unit and the second repeating unit U2 is a fluorine-free vinyl ether repeating unit.
