EPT is a thermal stable insulating substance 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 decreases operating and sagging, and enhances weatherability. The addition of mica to all varieties of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) drastically decreases penetration and increases holdout. The inclusion of mica in road and highway paints enhances wearability, provides great adhesion, and reduces flaking and cracking, also utilised to coat wallpaper since it imparts an desirable silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
