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 get over tackiness and sticking, In exterior home paints minimizes working and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) greatly decreases penetration and improves holdout. The inclusion of mica in road and freeway paints improves wearability, gives great adhesion, and lowers flaking and cracking, also employed to coat wallpaper since it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
