EPT is a thermal stable insulating materials 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 get over tackiness and sticking, In exterior property paints reduces working and sagging, and improves 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 increases holdout. The inclusion of mica in street and freeway paints enhances wearability, gives very good adhesion, and reduces flaking and cracking, also employed to coat wallpaper because it imparts an desirable silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
