​anodizing; metal treatment; coatings; aluminium treatment

Product Description

This 50% aqueous solution of 4-sulfophthalic acid is the key component of the preferred electrolyte for the production of "hard" anodic oxide coatings for aluminium-based alloys. These highly abrasion resistant coatings come in a number of colors, metallic and brownish gray, black, bronze and gold amking them suitable for achitectural usage. Anodizing with Pilot D-300 efficiently produces a range of protective and decorative oxide coatings, with moderate voltage and cooling requirements.
