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 defeat tackiness and sticking, In exterior property paints lowers working and sagging, and improves weatherability. The addition of mica to all types 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 street and highway paints enhances wearability, gives very good adhesion, and decreases flaking and cracking, also employed to coat wallpaper due to the fact it imparts an eye-catching silky or pearly luster, employed predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
