Mica, for use as a filler, is coated with a chlorinated hydrocarbon by enveloping mica flakes in a fluid medium comprising the chlorinated hydrocarbon and a liquid dispersant therefor, and then drying the flakes at load temperatures. The chlorinated hydrocarbon is distributed macroscopically uniformly throughout the mica, as a coating, but provides a microscopically higher level of chlorine at the edges of the mica flakes, assisting in binding the flakes to plastics materials such as polypropylene. |
