EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints lowers running and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) significantly lowers penetration and increases holdout. The inclusion of mica in street and highway paints increases wearability, gives excellent adhesion, and lowers flaking and cracking, also utilized to coat wallpaper because it imparts an appealing silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
