EPT is a thermal stable insulating content in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints minimizes managing and sagging, and improves weatherability. The addition of mica to all sorts of sealers for porous surfaces (such as wallboard, masonry, and concrete blocks) greatly minimizes penetration and improves holdout. The inclusion of mica in road and freeway paints enhances wearability, presents good adhesion, and decreases flaking and cracking, also utilised to coat wallpaper due to the fact it imparts an eye-catching silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
