MULTICOAT EFFECT AND/OR COLOUR PAINT SYSTEM AND METHOD FOR PRODUCING AND USING SAME Russian patent published in 2018 - IPC B05D5/00 B05D7/00 B32B27/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a multicoat effect and/or colour paint system, a method for producing same, as well as use of multicoat paint system. System is produced by (I) applying a primer coating composition to a substrate and optionally curing it, (II) applying a first pigmented basecoat coating composition (BL1) to the primer obtained in stage (I), (III) optionally applying a second pigmented basecoat coating composition (BL2) to the first basecoat film, obtained in stage (II), (IV) applying a transparent coating material composition (KL) based on at least one polyhydroxyl group-containing compound (A), and at least one polyisocyanate group-containing component (B) to the first basecoat film, obtained in stage (II), or if a second basecoat coating composition (BL2) has been applied to the second basecoat film, obtained in stage (III), and (V) jointly curing the first basecoat film, the second basecoat film, where present, and the transparent coating film. Transparent coating material composition (KL) comprises (i) at least one rheological assistant based on fumed silica and (ii) at least one polyisocyanate group-containing component.

EFFECT: technical result is obtaining a system that provides a good polishing capacity.
