EPT is a thermal stable insulating content in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to overcome tackiness and sticking, In exterior house paints lowers operating and sagging, and increases weatherability. The addition of mica to all kinds of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) significantly lowers penetration and increases holdout. The inclusion of mica in highway and highway paints enhances wearability, presents good adhesion, and minimizes flaking and cracking, also employed to coat wallpaper since it imparts an eye-catching silky or pearly luster, used predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
