EPT is a thermal steady insulating content in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to overcome tackiness and sticking, In exterior home paints lowers managing and sagging, and improves weatherability. The addition of mica to all kinds of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and increases holdout. The inclusion of mica in road and freeway paints increases wearability, provides great adhesion, and reduces flaking and cracking, also utilized to coat wallpaper since it imparts an attractive silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
