  • Publication number: 20250084260
    Abstract: Disclosed herein is an aqueous colloidal titanium dioxide dispersion preferably having a pH value in a range of 6.2 to 7.8 at 25° C. and including titanium dioxide particles, the titanium particles having a Z-average particle size in a range from 30 nm to 220 nm as determined by dynamic light scattering and a particle size distribution span [(D90-D10)/(D50)] in a range from 0.7 to 1.5; one or more dispersing agents comprising groups which bind to the titanium dioxide particles; one or more organic solvents; and if necessary, one or more pH value adjusting compounds. Further disclosed herein are a method of preparing such dispersions, a coating composition containing the components of such dispersions, coated substrates and methods of coating the substrates with such dispersions and a method of using of the dispersions in the manufacture of coating compositions.

  • Publication number: 20240327657
    Abstract: Disclosed herein is a multilayer coating including at least one ground coat layer, the at least one ground coat layer including at least one non-platelet-shaped titanium dioxide pigment (T); at least one midcoat layer on top of the at least one ground coat layer, and at least one clearcoat layer on top of the at least one midcoat layer; and having a lightness L* according to CIELab in the viewing angle range from ?15° to +45° of at least 80; in the viewing angle range from +75° to +110° of at least 70, if a metal effect pigment is contained in the midcoat layer; in the viewing angle range from +75° to +110° of at least 75, if no metal effect pigment is contained in the midcoat layer. Further disclosed herein are a method for producing such multilayer coating and a multilayer coated substrate.

  • Publication number: 20210348003
    Abstract: The present disclosure relates to an aqueous basecoat material including as binder, at least one aqueous, acrylate-based microgel dispersion (MD), and also at least one pigment paste including at least one color and/or effect pigment, and also as paste binder, at least one polymer of olefinically unsaturated monomers, where the polymer includes functional groups for nonionic stabilization of the polymer in water, and also functional groups selected from the group of silicon-containing, phosphorus-containing, and urea-containing groups, the aqueous basecoat material further including less than 0.5 wt %, based on its total weight, of synthetic phyllosilicates.
