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