Feldspar colour selection
Feldspar is a milled crystalline anhydrous sodium potassium aluminium silicate.
It has a high dry brightness, high hardness, good heat stability, is inert and is easy to disperse.
The main application for Feldspar is as a general filler in self-levelling floor screeds, paints, polymers, adhesives, polishes and rubbing compounds.
It is primarily used as an alternative to silica flour because it has good opacity - which reduces the requirement of white pigment in light coloured formulations.
