EPT is a thermal steady insulating content 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 house paints reduces managing and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and enhances holdout. The inclusion of mica in road and highway paints increases wearability, offers great adhesion, and minimizes flaking and cracking, also utilized to coat wallpaper simply because it imparts an eye-catching silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
