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 residence paints minimizes running and sagging, and enhances weatherability. The addition of mica to all sorts of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and increases holdout. The inclusion of mica in highway and highway paints enhances wearability, provides good adhesion, and decreases flaking and cracking, also used to coat wallpaper since it imparts an appealing silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
