Method of making cationic pigment slurries

摘要

Cationically dispersed slurries of alumina pigments, which formed by a process including the combination of one or more alumina pigments, a nonionic wetting agent or nonionic polymer and a cationic interfacial modifier in an aqueous medium in the absence of an acid dispersant. The slurries may be used in a method of manufacturing paper and paperboard products.
