Pigment preparation containing at least one pigment and at least one compound of the general formula CH&#x2014;(CH)&#x2014;CH&#x2014;O&#x2014;[(CH)&#x2014;O]&#x2014;H. The pigment preparation can be produced by dispersing and drying. It can be used for coloration and/or antistaticization in waterborne color and varnish systems, emulsion paints, printing inks, liquid-ink systems and coating systems.

Pigment preparation, method for producing the same and its use

Silanised, structurally modified silicas, characterised by groups fixed on the surface, the groups being alkylsilyl (SiCH, 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.

Silicas

Silanized, structurally modified, pyrogenically produced silicas, characterised by groups fixed to the surface, wherein the groups are dimethylsilyl and/or monomethylsilyl, are produced in that pyrogenically produced silica is treated by a known method with dimethyldichlorosilane and/or monomethyltrichlorosilane, the groups dimethylsilyl and/or monomethylsilyl being fixed on the surface of the pyrogenic silica, and is then structurally modified and optionally post-ground. They are used to improve scratch resistance in lacquers.

Silica

Functionalized, structurally modified silicas with 3-methacryloxypropylsilyl and/or glycidyloxypropylsilyl groups on the surface are prepared by mixing the silicas with the silane and heat-treating, destructuring and grinding the mixture. The silicas are employed in radiation-curing coatings.

Functionalized, structurally modified silicas

Functionalized silicas with 3-methacryloxypropylsilyl and/or glycidyloxypropylsilyl groups on the surface are prepared by mixing the silicas with the silane and heat-treating the mixture. The silicas are employed, for example, in solvent-containing coatings.

Functionalized silicas

Radiation-curing coating systems which contain a silanized silica, where the silane is hexamethyldisilazane, 3-methacryloxypropyltrialkoxysilane and/or glycidyloxypropyltrialkoxysilane as the silanizing agent. The radiation-curing coating systems can be used for coating derived timber boards, solid wood, wood veneers, parquet, decorative papers, decorative films, thermoplastics and thermosetting plastics, mineral and polymeric glasses, metals (for example aluminium, high-grade steel, phosphated, chromated and galvanized steel sheets, copper), lacquered surfaces, printing inks and leather.
