ALODUR® ESK - brown fused alumina
Robust, hard and angular grain for general and demanding industrial treatment. On impact it cuts the surface efficiently, removes corrosion, oxides, heat scale and old coatings, and creates a pronounced profile.

typical applications
Preparation before painting, metallising, bonding and protective systems; removal of corrosion and hard deposits; matting and roughening; industrial engraving. ESK is supplied in FEPA F/P grit sizes and special distributions according to the manufacturer's programme.
A FEPA designation does not represent a single grain diameter. The complete particle-size distribution in the current manufacturer's specification is decisive.
