EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to get over tackiness and sticking, In exterior home paints reduces running and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically lowers penetration and enhances holdout. The inclusion of mica in street and highway paints enhances wearability, provides great adhesion, and reduces flaking and cracking, also used to coat wallpaper simply 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 moist mica powder).
