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 slender coating on rubber surfaces to defeat tackiness and sticking, In exterior home paints decreases working and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) greatly lowers penetration and improves holdout. The inclusion of mica in road and freeway paints increases wearability, gives excellent adhesion, and reduces flaking and cracking, also used to coat wallpaper simply because it imparts an desirable silky or pearly luster, employed predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
