EPT is a thermal steady 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 overcome tackiness and sticking, In exterior house paints decreases running and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) greatly reduces penetration and enhances holdout. The inclusion of mica in highway and highway paints increases wearability, presents great adhesion, and minimizes flaking and cracking, also employed to coat wallpaper because it imparts an desirable silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
