EPT is a thermal steady insulating substance in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to get over tackiness and sticking, In exterior home paints minimizes working and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) greatly minimizes penetration and enhances holdout. The inclusion of mica in road and highway paints enhances wearability, offers good adhesion, and reduces flaking and cracking, also employed to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
