EPT is a thermal steady 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 property paints lowers operating 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) drastically reduces penetration and improves holdout. The inclusion of mica in highway and freeway paints enhances wearability, presents great adhesion, and reduces flaking and cracking, also utilized to coat wallpaper simply because 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 damp mica powder).
