EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints minimizes operating and sagging, and increases weatherability. The addition of mica to all kinds of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and enhances holdout. The inclusion of mica in street and freeway paints increases wearability, presents great adhesion, and lowers flaking and cracking, also used to coat wallpaper simply because it imparts an attractive silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
