EPT is a thermal stable insulating materials in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to defeat tackiness and sticking, In exterior residence paints decreases managing and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) tremendously reduces penetration and improves holdout. The inclusion of mica in street and highway paints increases wearability, provides good adhesion, and reduces flaking and cracking, also used to coat wallpaper simply because it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
