EPT is a thermal steady insulating content 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 home paints lowers working and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this kind of as wallboard, masonry, and concrete blocks) drastically lowers penetration and improves holdout. The inclusion of mica in highway and highway paints enhances wearability, provides very good adhesion, and minimizes flaking and cracking, also used to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
