EPT is a thermal secure insulating materials 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 defeat tackiness and sticking, In exterior home paints lowers managing and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and increases holdout. The inclusion of mica in street and highway paints improves wearability, presents good adhesion, and decreases flaking and cracking, also utilised to coat wallpaper simply because it imparts an eye-catching silky or pearly luster, used predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
