EPT is a thermal secure insulating content in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a thin coating on rubber surfaces to defeat tackiness and sticking, In exterior residence paints lowers working and sagging, and improves weatherability. The addition of mica to all kinds of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) greatly minimizes penetration and enhances holdout. The inclusion of mica in highway and highway paints improves wearability, offers good adhesion, and minimizes flaking and cracking, also utilised to coat wallpaper due to the fact it imparts an appealing silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We provide muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
