Dispersion of titanium dioxide in non‐aqueous media: Part 1

This series of articles is based on the new 64pp booklet prepared by the author, aided by many of his colleagues in Tioxide International Ltd, and published last month under the title “Dispersion of Tioxide Pigments in Non‐Aqueous Media”. The book describes the principles of dispersion and gives practical advice to help coatings chemists disperse Tioxide pigments in the most efficient and economical manner possible. Section A defines dispersion and gives a brief explanation of mechanisms that may be concerned in the production of a stable dispersed system. It presents an outline scheme for the formulation of millbases that can be applied to all combinations of titanium dioxide pigments and resins. The effects of resins, solvents, and “dispersing aids” are also considered. Section B describes the types of paintmaking machine used in the industry today. The sections of the original book to be ommitted from the series of articles to be published in the journal are those that it is considered have already been adequately covered in the literature.
