EPT is a thermal secure insulating material in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to defeat tackiness and sticking, In exterior home paints lowers working and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically reduces penetration and increases holdout. The inclusion of mica in road and freeway paints enhances wearability, provides great adhesion, and lowers flaking and cracking, also utilized to coat wallpaper because it imparts an eye-catching silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
