EPT is a thermal steady insulating material 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 reduces working and sagging, and enhances weatherability. The addition of mica to all varieties of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) significantly lowers penetration and improves holdout. The inclusion of mica in street and highway paints improves wearability, offers good adhesion, and decreases flaking and cracking, also utilized to coat wallpaper because it imparts an desirable silky or pearly luster, used predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
