The invention relates to a silane coating material and a process to produce silane coating. n To produce a silane coating material according to the preamble, in which the above-mentioned drawbacks are avoided, according to the invention a process to produce a silane coating is proposed where one or several silanes, which are not or only minimally pre-condensed, are charged with a reactant and the thus created coating material is applied onto a substrate and then hardened. n Surprisingly it has been shown that, through the reaction involving higher-molecular and only slightly pre-cross-linked silanes with a suitable reactant, a new class of coating materials can be created. According to the current state of the art, silanes are processed in sol-gel processes, where pre-condensated species are assumed. The approach according to the invention is advantageous insofar as the restrictions with respect to pot time no longer exist and, in addition, better features of the coating material are obtained, especially a high scratch-resistance. |
