Grinded Mica

Grinding of Mica Scrap properly cleaned by removing all types of foreign particles produces ground mica. They are tough and inert to most of the chemicals and thermal conditions while retaining elasticity and slipperiness far superior to conventional ground minerals or rocks.

Major applications includes Roof coating, Wall papers, Well-drilling mud, Paint pigment extender, fillers for plastic-rubber goods and flux material in welding electrodes.

Mica powder as a pigment is used in a binder like varnish or shellac to create metallic finishes. The advantage mica has over metal flakes is its inability to tarnish. It grows in a layered structure, kind of like an onion, and has a mother of pearl translucency. This is what gives mica powder its fantastic reflective quality. When these mica platelets are ground, they create a particle that is many faceted. Since mica is an inert mineral, it does not chemically react with any binder during or after application.

As with all pigment, the size of the particle of color is important and with some mica there is a choice between regular and micro which is extra finely ground. 

Mica can be mixed together for creativity and precision when matching and creating coatings. In the past, mixing of customized metallic coatings was hazardous because airborne metallic powders are very toxic. 

This makes for a more opaque and even surface. The pigment adheres to the surface of the binder. The binders of choice for this technique are the traditional linseed oil gilding size or the modern water based acrylic gilding sizes. These sizes can be pigmented with tinting pastes exploding creative possibilities.
