EPT is a thermal steady insulating content in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to conquer tackiness and sticking, In exterior residence paints decreases working and sagging, and improves weatherability. The addition of mica to all kinds of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) significantly decreases penetration and increases holdout. The inclusion of mica in highway and freeway paints improves wearability, presents excellent adhesion, and decreases flaking and cracking, also utilised to coat wallpaper due to the fact it imparts an eye-catching silky or pearly luster, employed predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
