EPT is a thermal secure 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 overcome tackiness and sticking, In exterior property paints decreases running and sagging, and enhances weatherability. The addition of mica to all sorts of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) greatly minimizes penetration and increases holdout. The inclusion of mica in road and freeway paints enhances wearability, offers very good adhesion, and decreases flaking and cracking, also used to coat wallpaper simply because it imparts an attractive 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).
