Abstract:
1. Method for producing an abhesive coating from cross-linked inorganic nanoparticles, and additions of polyorganosiloxanes according to the sol-gel method, characterized by the following steps: preparation of an inorganic nanosol by the hydrolysis of an alkoxysilane and partial condensation and by colloidally dispersing the inorganic nanoparticles in an alcohol to form the inorganic nanosol, modification of the nanosol by the addition of polyorganosiloxanes, wherein one or more of the added polyorganosiloxanes have vinyl groups and/or epoxy groups and/or SiH groups, addition of additives which promote crosslinking applying the modified nanosol on a surface and forming three-dimensional networks of the inorganic nanoparticles and of the polyorganosiloxanes by a heat treatment.
