Abstract (en)

[origin: WO9938034A1] An adhesion-enhancing coating is provided that includes an organic matrix with inorganic oxide particles dispersed therein. The coating is formed from a precursor composition that includes a ceramer composition. A ceramer composition can include at least one ethylenically unsaturated monomer, an optional organofunctional silane monomer coupling agent, and inorganic colloidal particles that at least include silica. An alternative ceramer composition includes an organofunctional silane monomer coupling agent and inorganic colloidal particles that at least include silica.
