EPT is a thermal secure insulating substance in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to conquer tackiness and sticking, In exterior home paints reduces working and sagging, and enhances weatherability. The addition of mica to all kinds of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically lowers penetration and increases holdout. The inclusion of mica in street and highway paints enhances wearability, gives great adhesion, and decreases flaking and cracking, also utilized to coat wallpaper since it imparts an desirable silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
