EPT is a thermal stable insulating substance in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints decreases working 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) significantly lowers penetration and increases holdout. The inclusion of mica in highway and highway paints improves wearability, presents very good adhesion, and decreases flaking and cracking, also employed to coat wallpaper simply because it imparts an desirable silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
