  • Soft-settling silica flatting agent
    Patent number: 4263051
    Abstract: Finely divided silica is used as a flattening agent to reduce gloss in lacquers and varnishes, but untreated silica tends to settle out of certain lacquers and varnishes to form a hard layer that is resistant to redispersion. Treatment of the silica with a reactive organopolysiloxane such as methyl hydrogen polysiloxane reduces the tendency of the silica to settle and renders it more easily redispersible. The treated silica may be incorporated into known lacquers, varnishes, and other coating compositions.
