EPT is a thermal steady insulating substance in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to get over tackiness and sticking, In exterior property paints reduces managing and sagging, and enhances weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) significantly reduces penetration and improves holdout. The inclusion of mica in road and freeway paints enhances wearability, offers excellent adhesion, and minimizes flaking and cracking, also used to coat wallpaper due to the fact it imparts an attractive silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
