EPT is a thermal stable insulating substance in the welding-rod coatings EPT and also used in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to defeat tackiness and sticking, In exterior house paints minimizes working and sagging, and enhances weatherability. The addition of mica to all types of sealers for porous surfaces (these kinds of as wallboard, masonry, and concrete blocks) significantly reduces penetration and enhances holdout. The inclusion of mica in road and highway paints increases wearability, provides excellent adhesion, and minimizes flaking and cracking, also utilized to coat wallpaper because it imparts an attractive silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
