EPT is a thermal stable insulating materials 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 house paints minimizes running and sagging, and improves weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) drastically minimizes penetration and enhances holdout. The inclusion of mica in road and freeway paints improves wearability, offers great adhesion, and decreases flaking and cracking, also employed to coat wallpaper because it imparts an eye-catching silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
