Two-component coating composition, method for homogeneously mixing a curing component into a binder component, and use of nano pigments for providing a marker color to a curing component

Abstract

The present disclosure relates to a two-component coating composition comprising: i) a binder component comprising an isocyanate-curable binder polymer; and ii) a curing component comprising an isocyanate-functional curing agent and a color pigment having a D50 particle size in the range of from 10 to 200 nm and a D95 particle size in the range of from 30 to 300 nm, wherein the D50 and D95 particle size are measured by laser diffraction according to ISO 13320 using the Mie theory, wherein the curing component is free of any further color pigment. The disclosure further relates to a method for homogeneously mixing a curing component comprising an isocyanate-functional curing agent colored with nanopigments into a binder component, and to use of nanopigments for providing a marker color to a curing component comprising an isocyanate-functional curing agent.
