EPT is a thermal stable insulating content in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to overcome tackiness and sticking, In exterior house paints lowers operating and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) significantly decreases penetration and increases holdout. The inclusion of mica in street and highway paints increases wearability, provides very good adhesion, and lowers flaking and cracking, also employed to coat wallpaper simply because it imparts an attractive silky or pearly luster, used predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
