EPT is a thermal secure insulating material 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 defeat tackiness and sticking, In exterior home paints reduces operating and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically reduces penetration and enhances holdout. The inclusion of mica in highway and freeway paints increases wearability, presents good adhesion, and reduces flaking and cracking, also utilised to coat wallpaper because it imparts an attractive silky or pearly luster, used predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand damp mica powder).
