Nonionic surfactant treated clays, methods of making same, water-based paints, organic solvent-based paints and paper coatings containing same

摘要

A dry clay product useful as a filler in organic solvent-based paints and water-based paints to impart improved gloss to dried films of the paints and in paper coatings to improve the gloss ink holdout properties of the coating and comprising a mixture of a major amount of kaolin clay particles and a minor amount of a nonionic surfactant compatible with water and oil and having an HLB value in the range of 3 to 15. Methods of making the novel clay product and coating materials including paints and paper coatings containing same.
