PCT No. PCT/EP94/03336 Sec. 371 Date May 6, 1996 Sec. 102(e) Date May 6, 1996 PCT Filed Oct. 10, 1994 PCT Pub. No. WO95/13326 PCT Pub. Date May 18, 1995A process is disclosed for the production of compounds based on hydrolyzable silanes containing epoxy groups. The process involves adding one of the following substances to a pre-hydrolyzed silicon compound A with at least one hydrolytically non-separable group which includes an epoxy ring in the presence of an alcoholate of zirconium or aluminum: i) a particulate substance B which can be selected from oxides, oxyhydrates, nitrides or carbides of Si, Al and B, and of transition metals, the particle size being 1-100 nm; ii) a surface-active agent, preferably non-ionic; iii) an aromatic polyol with an average molecular weight not exceeding 1000, the resulting compounds being useful to produce coatings and molded bodies with a range of properties, in particular high scratch resistance, lasting hydrophilic characteristics, corrosion resistance, good adhesion and transparency.
