EPT is a thermal secure insulating materials in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to conquer tackiness and sticking, In exterior house paints lowers working and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) significantly minimizes penetration and improves holdout. The inclusion of mica in road and highway paints enhances wearability, offers very good adhesion, and reduces flaking and cracking, also utilized to coat wallpaper due to the fact it imparts an eye-catching silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
