Abstract:
Process for the production of compositions based on hydrolyzable silanes having epoxy groups, comprising:adding to said composition(i) a particulate material B selected from the group consisting of oxides, oxohydrates, nitrides and carbides of Si, Al, B and of transition metals, and having a particle size ranging from 1 to 100 nm; and optionally(ii) a surfactant C; and/or(iii) an aromatic polyol D having an average molecular weight not exceeding 1000; to at least one prehydrolyzed silicon compound A having at least one radical bonded directly to Si and not being removable hydrolytically and including an epoxide ring in the presence of a titanium alkoxide or aluminum tributoxyethanolate in an amount not exceeding 70% by moles based on the total of hydrolyzable compounds employed, provided that the hydrolysis of the silicon compound A may also be effected in the presence of said particulate material B.
