Abstract
A process for preparing a high solids paste dispersion of fine particle size solid material in a vehicle which comprises premixing the solid material with the vehicle and a deagglomerating agent. The proportions of solid material, vehicle and deagglomerating agent are such that the premix remains a dry discrete flowable powder. The premix is then passed through a colloid mill which converts the powder to a paste dispersion in the form of a coherent mass in one pass through the mill.
