EPT is a thermal stable insulating material in the welding-rod coatings EPT and also utilised 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 decreases operating and sagging, and enhances weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) greatly reduces penetration and improves holdout. The inclusion of mica in street and freeway paints enhances wearability, presents great adhesion, and minimizes flaking and cracking, also used to coat wallpaper simply because it imparts an attractive silky or pearly luster, employed predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
