The structurally modified and pyrolyzed silanized silica, characterized by dimethylsilyl groups and / or monomethylsilyl groups fixed to the surface, may be used to convert silica prepared by pyrolysis into dimethyldichlorosilane and / or monomethyltriclo. It is prepared by treating with a known method using rosilane to fix the dimethylsilyl group and / or monomethylsilyl group to the surface of the silica produced by pyrolysis, then structurally modifying and optionally post-milling. These are used to improve the scratch resistance of the lacquer.n n n Dimethylsilyl, monomethylsilyl, silanized silica, scratch resistance, lacquer, silica produced by pyrolysis, post grinding. |
