Mica Powder

Mica Flakes is indispensably used in the manufacture of pearlescent pigments (pearl luster pigments) which consists of natural mica flakes coated with titanium dioxide and/or iron oxide. They possess high reflective and refractive index imparting natural pearl-like luster and magical gloss with abundant fascinating colours and enticing appearance. The unique characteristics makes it most distinctive and deeply promising in the present age. Pearlescent pigments are applied to numerous industries like paint, plastic, coating, printing ink, leather, cosmetic, dyeing, ceramic, rubber and paper.

Mica Powder is well recognized for use in the manufacture of welding electrodes as a flux coating on the metal wire. Mica is added to the flux with which welding electrodes are coated as arc stabilizers, weld pool protectors, fluxing agents, slag modifiers, binders, extrusion agents and pigments. Potassium also facilitates re-ignition of the welding rods after interruptions to the current. The Mica coating provides two distinct types of protection. Firstly, it serves in forming a fusible slag and a good seal at the fusion zone of the arc. Secondly, it resists the action of heat, gaseous and other surrounding atmospheric oxidation. In fact, it is the nature of mica coating that largely determines the quality of welding electrodes.
