EPT is a thermal secure 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 house paints lowers running and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously reduces penetration and enhances holdout. The inclusion of mica in highway and highway paints enhances wearability, offers very good adhesion, and minimizes 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 wet mica powder).
