Abstract

While grey waterborne acrylic polyurethane coatings are widely used in passenger cars for rail transit,the special properties of carbon black particles lead to discoloration in the process of production and storage and suitable wetting dispersant and organic bentonite can prevent discoloration in the process of coating production and storage in this paper,different wetting dispersants and organic bentonite will be studied to improve the flaw that grey waterborne paint easily discolors.
