EPT is a thermal steady insulating material in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to overcome tackiness and sticking, In exterior house paints reduces working and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) greatly lowers penetration and improves holdout. The inclusion of mica in street and freeway paints improves wearability, presents great adhesion, and lowers flaking and cracking, also utilised to coat wallpaper since 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).
