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 slender coating on rubber surfaces to defeat tackiness and sticking, In exterior home paints lowers managing and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) greatly decreases penetration and increases holdout. The inclusion of mica in highway and freeway paints increases wearability, offers good adhesion, and reduces flaking and cracking, also utilized to coat wallpaper simply because it imparts an eye-catching silky or pearly luster, used predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
