Self-crosslinking compositions based on fluorine-containing polycondensates |
摘要 |
The invention relates to a method for coating a substrate according to which a self-crosslinking coating composition is produced on the basis of a) at least one hydrolysable silane with at least one nonhydrolysable substituent, said silane having one or more electrophilic groups X on at least one nonhydrolysable substitutent, b) at least one hydrolysable silane with at least one nonhydrolysable substituent, said silane having one or more nucleophilic groups Y on at least one nonhydrolysable substituent, c) at least one hydrolysable silane with at least one nonhydrolysable carbonic group that has an average of 2 to 30 fluorine atoms that are bound to one or more aliphatic carbon atoms that are separated from the silicon atom by at least two atoms. The silanes (a), (b) and/or (c) are optionally precondensed and either the silanes (a) may be completely or partially replaced by organic compounds with at least two groups X or the silanes (b) may be completely or partially replaced by organic compounds with at least two groups Y. The self-crosslinking coating composition is then applied to a substrate and allowed to cure at ambient temperature (below 40° C.) to form a coating.
