Definitions

  • Particularly preferred nanoparticulate dispersible particles of the type according to the invention are lithium molybdate particles having an average particle size of from 5 to 60 nm.
  • the mixing of the aqueous and the organic phase is carried out with stirring or by supplying increased energy, for example by high-pressure homogenization, rotor-stator systems, Turrax, ultrasound, magnetic stirrers or other dispersing methods, preferably with stirring by means of conventional stirrers, such as magnetic stirrers or rotor-stator systems.
  • a dispersion of 2750 ppm nanoparticulate lithium molybdate in butyl acetate was prepared as follows. 6 mL of butyl acetate with 50 g / L of Pluronic PEI 0500 were admixed with 290 ⁇ L of 5% by weight aqueous lithium molybdate solution. The emulsion was shaken and heated to 80 ° C. three times and cooled again at RT. The addition of about 1.5 g of silica gel beads for dehydration was carried out at 8O 0 C on the last heating. After 10 minutes, the supernatant dehydrated dispersion was removed from the desiccant.
  • the catalyst lithium molybdate (c) was obtained as a coarsely crystalline salt from Aldrich and used according to the invention preparation of the nanoparticulate form in the stated amount of butyl acetate in the inventive example. It is contained in the amount of butyl acetate in the example according to the invention. Based on the solids content of the paint system, the amount of lithium molybdate was 250 ppm in the example according to the invention.
