EPT is a thermal stable insulating material in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to conquer tackiness and sticking, In exterior residence paints reduces working and sagging, and increases weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously lowers penetration and enhances holdout. The inclusion of mica in street and highway paints enhances wearability, provides great adhesion, and reduces flaking and cracking, also utilized to coat wallpaper because it imparts an appealing 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).
