EPT is a thermal steady insulating content in the welding-rod coatings EPT and also utilized in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slender coating on rubber surfaces to defeat tackiness and sticking, In exterior property paints lowers working and sagging, and increases weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) greatly reduces penetration and improves holdout. The inclusion of mica in highway and freeway paints enhances wearability, presents very good adhesion, and lowers flaking and cracking, also used to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand soaked mica powder).
