Feldspar 5

Feldspar 5 by Boud Minerals is milled crystalline anhydrous sodium potassium aluminum silicate. It exhibits high dry brightness, high hardness, good heat stability, inertness and easy dispersibility. Provides protection against extreme weathering corrosion, increase in viscosity and wear properties. Feldspar 5 is primarily used as an alternative to silica flour because it has good opacity which reduces the requirement of white pigment in light colored formulations. Used in paints.
