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