In dry grinding of pigments intended for water dispersion, surface active agents are often used. Their main purpose in this application is to improve the degree of dispersion. For that reason, Emulsol P is often used. Pigments are often coated with an Oleophilic layer. The grinding of dry pigments into the oily vehicle is one of the most important steps in the manufacture of coating materials. The physical chemistry of this process has been intensively studied from both the practical and theoretical point of view & Emulsol P has been found to be of greater use here. Emulsol P is a dark brown colored substance insoluble in water but soluble in most of the solvents and oil media. However, in acidic water, it forms a dispersion showing cationic characteristic. Emulsol P can be used as an emulsifier in the paint industry.
