EPT is a thermal steady insulating material 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 defeat tackiness and sticking, In exterior property paints reduces working and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) greatly lowers penetration and increases holdout. The inclusion of mica in highway and highway paints increases wearability, presents excellent adhesion, and decreases flaking and cracking, also employed to coat wallpaper simply because it imparts an eye-catching silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
