EPT is a thermal steady 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 get over tackiness and sticking, In exterior property paints minimizes working and sagging, and increases weatherability. The addition of mica to all sorts of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) tremendously reduces penetration and improves holdout. The inclusion of mica in street and highway paints enhances wearability, provides very good adhesion, and minimizes flaking and cracking, also utilised to coat wallpaper due to the fact it imparts an attractive silky or pearly luster, used predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
