An organic-inorganic hybrid surface adhesion promoter having the general formula, A-B, wherein A is hydrolyzed and polycondensed from a trioxysilane R-Si(OR′) 3 or its mixture with one or two more silanes, where R′ is methyl, ethyl or propyl, and where R is an organic group of methacrylate, epoxy, amine, isolyante, hydroxide or non-halogens or halogens containing alkyl, alkenyl, aryl, alkylary or arylalky, and wherein B is hydrolyzed and polycondensed from an alkoxy silane, chloride silane, or alkoxy or chloride metal compound, whereby B reacts with a substrate to form a uniting group which is selected from the group consisting of Si—O—Si, M-O-M, M-O—S and Si—O-M, M being a metal atom. |
