ABSTRACT OF THE DISCLOSURE Latex-based coating materials are prepared frequently by compounding the latex with large quantities of calcium carbonate fillers. Whenever these fillers contain water-soluble calcium and magnesium compounds as impurities latices prepared with anionic emulsifiers are made more unstable, apparently because of reaction between these impurities and the emulsifier. This instability can be overcome by including in the latex a water-soluble fluoride such as ammonium or potassium fluoride in an amount generally under 5 parts by weight per 100 parts dry weight of latex. The process involves adding such a fluoride in an amount sufficient to stabilize the latex, generally under 5 parts per hundred of latex, dry weight.
