EPT is a thermal steady insulating content in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to get over tackiness and sticking, In exterior home paints reduces managing and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) greatly reduces penetration and increases holdout. The inclusion of mica in road and freeway paints improves wearability, presents very good adhesion, and lowers flaking and cracking, also used to coat wallpaper because it imparts an desirable silky or pearly luster, employed predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
