EPT is a thermal secure insulating material in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to conquer tackiness and sticking, In exterior home paints decreases working and sagging, and increases weatherability. The addition of mica to all kinds of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) greatly decreases penetration and enhances holdout. The inclusion of mica in road and freeway paints increases wearability, offers good adhesion, and reduces 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 supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
