EPT is a thermal stable insulating material in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a skinny coating on rubber surfaces to defeat tackiness and sticking, In exterior home paints lowers operating and sagging, and enhances weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically reduces penetration and increases holdout. The inclusion of mica in highway and highway paints increases wearability, provides great adhesion, and decreases flaking and cracking, also employed to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
