What is described is a method for producing a thermally shaped substrate coated with a sol-gel coating material, in which the sol-gel coating material comprises one or more hydrolyzable silanes, which may have been hydrolyzed to form a precondensate, and, if desired, a crosslinking agent, at least some of the hydrolyzable silanes containing on a non-hydrolyzable substituent a functional group by way of which crosslinking is possible, and in whichA) the sol-gel coating material is applied to a thermally shapable substrate,B) the applied sol-gel coating material is partially precrosslinked and/or dried,C) the substrate coated with the sol-gel coating material is subsequently shaped thermally, andD) during and/or after the thermal shaping the sol-gel coating material is cured completely by means of thermal or photochemical crosslinking. |
