Abstract

See full text

An aqueous carbon black millbase, an aqueous carbon black liquid coating, and a method of making the millbase and liquid coating are provided. The carbon blacks are modified carbon blacks that are engineered to be able to be stirred into an aqueous vehicle without high energy milling of the carbon black. The modified carbon blacks include low organic treatment levels and the millbase and liquid coating do not require large quantities of dispersant. The resulting coatings exhibit excellent viscosity, color, hiding power and stability.
