EPT is a thermal steady insulating content in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to get over tackiness and sticking, In exterior property paints decreases running and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) drastically decreases penetration and increases holdout. The inclusion of mica in street and highway paints enhances wearability, offers very good adhesion, and decreases flaking and cracking, also utilized to coat wallpaper simply because it imparts an eye-catching silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
