EPT is a thermal secure insulating materials 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 operating and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) drastically lowers penetration and increases holdout. The inclusion of mica in highway and freeway paints improves wearability, gives good adhesion, and decreases flaking and cracking, also utilised to coat wallpaper since it imparts an desirable silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
