EPT is a thermal stable insulating substance in the welding-rod coatings EPT and also employed in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to conquer tackiness and sticking, In exterior home paints lowers managing and sagging, and improves weatherability. The addition of mica to all varieties of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) significantly minimizes penetration and enhances holdout. The inclusion of mica in highway and highway paints enhances wearability, offers good adhesion, and reduces flaking and cracking, also utilised to coat wallpaper because it imparts an eye-catching silky or pearly luster, utilized predominantly in paint, plastics and rubber.
We source muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
