EPT is a thermal stable insulating material in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to conquer tackiness and sticking, In exterior residence paints lowers running and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) tremendously reduces penetration and enhances holdout. The inclusion of mica in highway and highway paints improves wearability, provides good adhesion, and decreases flaking and cracking, also utilized to coat wallpaper because it imparts an appealing 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).
