Abstract
The resistance of particulate material to clumping or solidification at below-freezing temperatures is improved by applying to the particles a coating of a polymer emulsion in water which drys to a water-insoluble film. A freeze-point-depressing substance is preferably combined with the emulsion in order to prevent the emulsion itself from freezing at the temperatures to which the particulate material is subjected. It is believed that said coating minimizes the strength of adhesion between the particles and any ice which may form between them and also minimizes the strength of such ice.
