EPT is a thermal stable insulating material in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints decreases working and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) drastically decreases penetration and increases holdout. The inclusion of mica in street and freeway paints improves wearability, gives great adhesion, and decreases flaking and cracking, also employed to coat wallpaper due to the fact it imparts an appealing 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).
