Product Details

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.

The dictionary defines mica as 'A class of silicates having a prismatic angle 120o, eminently perfect basal cleavage, affording thin tough laminae or scales, colorless to jet black, transparent to translucent, of widely varying chemical composition, and crystallising in the monoclinic system'.
In brief, mica is a generic term applied to a group of a complex aluminosilicate minerals having a sheet or plate like structure with different chemcial compositions and physical properties. All micas from from flat six-sided monoclinical crystals with a remarkable cleavage in the direction of the large surfaces,which permits them to split easily into optically flat films, as thin as one micron in thickness. When split into thin films, they remain tough and elastic even at high temperature.
What makes micas so important to command such a unique position ? Because it had been gifted with exceptional values. It possesses some of the most outstanding combination of chemcial, physical, electrical, thermal and mechanical properties which are not found in any other product.
Physically: Mica is transparent, optically flat, easily splittable into thin films along its cleavage, colourless in thin sheets, resilient and incompressible.
