EPT is a thermal steady insulating substance 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 get over tackiness and sticking, In exterior home paints reduces working and sagging, and improves weatherability. The addition of mica to all types of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) significantly minimizes penetration and enhances holdout. The inclusion of mica in highway and freeway paints increases wearability, presents good adhesion, and decreases flaking and cracking, also used to coat wallpaper since it imparts an desirable silky or pearly luster, used predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
