EPT is a thermal stable insulating materials 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 house paints lowers running and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) significantly lowers penetration and increases holdout. The inclusion of mica in highway and freeway paints enhances wearability, offers good adhesion, and reduces flaking and cracking, also employed to coat wallpaper simply because it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
