EPT is a thermal steady 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 defeat tackiness and sticking, In exterior home paints lowers working 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) significantly minimizes penetration and improves holdout. The inclusion of mica in street and highway paints increases wearability, provides good adhesion, and lowers flaking and cracking, also used to coat wallpaper since it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
