EPT is a thermal steady insulating materials in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to defeat tackiness and sticking, In exterior home 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) significantly lowers penetration and increases holdout. The inclusion of mica in highway and freeway paints enhances wearability, provides great adhesion, and decreases flaking and cracking, also utilised to coat wallpaper simply because it imparts an desirable silky or pearly luster, employed predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
