EPT is a thermal stable insulating content in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints lowers running and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) tremendously lowers penetration and improves holdout. The inclusion of mica in road and freeway paints increases wearability, provides good adhesion, and decreases flaking and cracking, also utilised to coat wallpaper because it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
