EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints decreases operating and sagging, and increases 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 improves holdout. The inclusion of mica in road and freeway paints increases wearability, provides excellent adhesion, and lowers flaking and cracking, also utilised to coat wallpaper since it imparts an appealing silky or pearly luster, employed predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
