Abstract (en)

[origin: DE19909877A1] The invention relates to a sol-gel coating material containing (A) an acrylate copolymer solution containing at least one acrylate copolymer (A1); (B) a parent varnish which can be prepared by hydrolysis and condensation of at least one hydrolysable silane (B1) of the general formula (I) SiR4, in which the variable R = hydrolysable groups, hydroxy groups and non-hydrolysable groups, subject to the condition that there should be at least one, preferably two, hydrolysable groups; and (C) a sol which can be prepared by hydrolysis, condensation and complexing of at least one hydrolysable silane (B1) of the general formula (I) and at least one hydrolysable metal compound (C1) of the general formula (II) MRn, in which the variables and the index have the following meanings: M = aluminium, titanium or zirconium; R = hydrolysable groups, hydroxy groups and non-hydrolysable groups, subject to the condition that there should be at least one, preferably two, hydrolysable groups; and n = 3 or 4.
