EPT is a thermal secure insulating material in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to conquer tackiness and sticking, In exterior home paints reduces running and sagging, and improves weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) greatly lowers penetration and enhances holdout. The inclusion of mica in highway and highway paints increases wearability, presents good adhesion, and decreases flaking and cracking, also employed to coat wallpaper simply because it imparts an appealing silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
