<p>Sepg. agents consisting of (A) a natural mineral silicate, e.g. talc, asbestos, kaolin, clay, carbonate e.g. chalk or metal oxide e.g. MgO or Al2O3 and (B) a soln. of synthetic rubber in organic solvent. Used for dusting of organic materials, e.g. raw or compounded rubber, plastics etc. to prevent adhesion and blocking.
