EPT is a thermal secure insulating content in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to get over tackiness and sticking, In exterior house paints reduces operating and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) greatly decreases penetration and increases holdout. The inclusion of mica in road and highway paints improves wearability, gives great adhesion, and lowers flaking and cracking, also used to coat wallpaper simply because it imparts an desirable silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
