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 overcome tackiness and sticking, In exterior home paints lowers operating and sagging, and improves weatherability. The addition of mica to all kinds of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) tremendously minimizes penetration and enhances holdout. The inclusion of mica in road and freeway paints enhances wearability, offers very good adhesion, and lowers flaking and cracking, also used to coat wallpaper since it imparts an attractive 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).
