EPT is a thermal steady insulating substance 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 overcome tackiness and sticking, In exterior house paints reduces managing and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically reduces penetration and enhances holdout. The inclusion of mica in street and freeway paints improves wearability, presents great adhesion, and decreases flaking and cracking, also utilised to coat wallpaper due to the fact it imparts an attractive silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
