Abstract:
Silanised, structurally modified silicas, characterised by groups fixed on the surface, the groups being alkylsilyl (SiCnH2n+1, with n=2-18). They are produced in that pyrogenically produced silicas are treated with the silanising agent and structurally modified. They are used to improve scratch resistance in lacquers.
