EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to get over tackiness and sticking, In exterior residence paints reduces managing 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) greatly minimizes penetration and enhances holdout. The inclusion of mica in street and freeway paints enhances wearability, provides great adhesion, and lowers flaking and cracking, also employed to coat wallpaper because it imparts an eye-catching silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
