Application
Mica powder is a thermal stable ( 500<C~1375<C) insulating material
in the welding-rod coatings industries and also used in caulking
compounds, lubricants, greases, dry-powder fire extinguishers,
as a thin coating on rubber surfaces to overcome tackiness and
sticking, In exterior house paints reduces running and sagging,
and improves weatherability. The addition of mica to all types
of sealers for porous surfaces (such as wallboard, masonry,
and concrete blocks) greatly reduces penetration and improves
holdout. The inclusion of mica in road and highway paints improves
wearability, gives good adhesion, and reduces flaking and cracking,
also used to coat wallpaper because it imparts an attractive
silky or pearly luster, used predominantly in paint, plastics
and rubber.
