EPT is a thermal stable 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 get over tackiness and sticking, In exterior residence paints lowers managing and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) drastically decreases penetration and increases holdout. The inclusion of mica in highway and freeway paints improves wearability, provides very good adhesion, and minimizes flaking and cracking, also used to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, used predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
