Abstract

A 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; PA1 ii) a surface-active agent, preferably non-ionic; PA1 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.
