EPT is a thermal steady insulating material in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints reduces operating and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) drastically lowers penetration and enhances holdout. The inclusion of mica in road and freeway paints enhances wearability, provides very good adhesion, and minimizes flaking and cracking, also used to coat wallpaper since it imparts an attractive silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
