EPT is a thermal stable insulating substance 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 minimizes working and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) greatly reduces penetration and enhances holdout. The inclusion of mica in road and freeway paints enhances wearability, gives very good adhesion, and reduces flaking and cracking, also employed to coat wallpaper since it imparts an desirable silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
