EPT is a thermal stable insulating substance 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 conquer tackiness and sticking, In exterior home paints reduces working and sagging, and enhances weatherability. The addition of mica to all varieties of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) drastically lowers penetration and improves holdout. The inclusion of mica in highway and highway paints enhances wearability, provides great adhesion, and decreases flaking and cracking, also employed to coat wallpaper due to the fact it imparts an desirable silky or pearly luster, used predominantly in paint, plastics and rubber.
We offer muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand wet mica powder).
