EPT is a thermal steady insulating content 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 conquer tackiness and sticking, In exterior home paints lowers operating and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically decreases penetration and enhances holdout. The inclusion of mica in street and highway paints improves wearability, gives great adhesion, and lowers flaking and cracking, also employed to coat wallpaper since it imparts an desirable silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
