EPT is a thermal secure insulating material in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints decreases working and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) significantly minimizes penetration and increases holdout. The inclusion of mica in street and highway paints enhances wearability, provides good adhesion, and lowers flaking and cracking, also used to coat wallpaper simply because it imparts an attractive silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
