EPT is a thermal stable insulating substance 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 conquer tackiness and sticking, In exterior property paints decreases 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) drastically lowers penetration and enhances holdout. The inclusion of mica in street and freeway paints enhances wearability, presents excellent adhesion, and lowers flaking and cracking, also utilised to coat wallpaper since it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
