EPT is a thermal steady insulating materials 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 overcome tackiness and sticking, In exterior residence paints reduces working and sagging, and improves weatherability. The addition of mica to all types of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) greatly decreases penetration and increases holdout. The inclusion of mica in road and freeway paints enhances wearability, gives excellent adhesion, and reduces flaking and cracking, also utilised to coat wallpaper simply because it imparts an desirable silky or pearly luster, used predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
