EPT is a thermal stable insulating material in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to defeat tackiness and sticking, In exterior home paints lowers operating and sagging, and improves weatherability. The addition of mica to all kinds of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) significantly lowers penetration and enhances holdout. The inclusion of mica in highway and freeway paints enhances wearability, gives excellent adhesion, and lowers flaking and cracking, also employed to coat wallpaper simply because it imparts an desirable silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
