Micronised Muscovite Mica is extensively used as a pigment extender in various paints and coatings. It is a tough, flexible and transparent mineral that can be ground to less than a micron sieve mesh.
Mica particles brighten the tone of the coloured pigments, at the same time, transmit and reflect light resulting in proven decorative effects and design. It increases the gloss of a paint more effectively than spherical or irregularly shaped filler particles of an equivalent size product. Mica also optimize the effect of other pigments by ensuring that the pigment particles are evently spaced in the dried paint film.As mica has good suspension properties, its inclusion reduces running, sagging and settling of paints, as well as, improves weatherability and brushability. The addition of mica makes it possible to redisperse the settled pigment easily at any stage of production by simple stirring.
