Corrosion Mechanism: If a standard 12µm coating has a single pore, corrosion concentrates there, forming a deep crater that reaches the substrate within 48 hours. In the exclusive 6µm system, the current is spread across millions of pores, resulting in superficial "white rust" only after 200+ hours.
Architectural hardware and visible automotive suspension parts require zero gloss variation. Exclusive X02 processes utilize computer-controlled current density to ensure that a 6µm coating looks identical on a flat washer and a deep recessed hole—something standard barrel plating cannot achieve. din 509e06x02 exclusive
