EPT is a thermal stable 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 conquer tackiness and sticking, In exterior home paints reduces managing and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) significantly lowers penetration and enhances holdout. The inclusion of mica in road and highway paints improves wearability, offers great adhesion, and minimizes flaking and cracking, also used to coat wallpaper due to the fact 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).
