Mica
Pigment are coated with mica to make pearl pigments.
For making wall paper and coated paper.
To make good anti corrosive paint, primer, under coat, water based paints exterior coating, chemical resistant coating etc. Used in marine paints and aluminium paints. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension, reduces chalking, prevents shrinking and shearing of the paint film, increases resistance of the paint film to water penetration and weathering, and brightens the tone of colored pigments. Mica also promotes paint adhesion in aqueous and oleoresinous formulations.
Used in plastic Industry as a filler an mica improves electrical and thermal resistance and boost in insulation properties. Mica has innumerable uses in many industries like fire extinguishers, oil drilling, construction chemical, building material, lubricants, adhesives, and foundries. The plastics industry used dry-ground mica as an extender and filler, especially in parts for automobiles as lightweight insulation to suppress sound and vibration. Mica is used in plastic automobile fascia and fenders as a reinforcing material, providing improved mechanical properties and increased dimensional stability, stiffness, and strength. Mica-reinforced plastics also have high-heat dimensional stability, reduced warpage, and the best surface properties of any filled plastic composite.
Ground mica is used in the well-drilling industry as an additive to drilling fluids. The coarsely ground mica flakes help prevent the loss of circulation by sealing porous sections of the drill hole.
The rubber industry used ground mica as an inert filler and mold release compound in the manufacture of molded rubber products, such as tires and roofing. The platy texture acts as an antiblocking, antisticking agent. As a rubber additive, mica reduces gas permeation and improves resiliency.
