Aluminum Pigments for Powder Coatings

The manufacture of aluminum pigments involves a specialized ball-milling process as the first stage. Here the atomized aluminum is ball-milled in the presence of solvent and a lubricant for a period of five to 40 hours. The lubricant is employed to prevent "cold welding" of the aluminum particles and thus avoid agglomerates.
