EPT is a thermal secure insulating material in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints decreases working and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously decreases penetration and improves holdout. The inclusion of mica in highway and freeway paints enhances wearability, provides great adhesion, and minimizes flaking and cracking, also used to coat wallpaper since it imparts an appealing silky or pearly luster, employed predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
