EPT is a thermal secure insulating material 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 home paints lowers running and sagging, and enhances weatherability. The addition of mica to all varieties of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) greatly decreases penetration and enhances holdout. The inclusion of mica in road and freeway paints improves wearability, offers great adhesion, and minimizes flaking and cracking, also employed to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
