APPLICATION & FEATURES: • acidic liquid • additive for hard anodizing electrolytes based on sulphuric acid (DC-process) • compared to low temperature anodizing processes economically advantageous • reduces the dissolution of the oxide film under unfavorable anodizing conditions • improves the uniformity of the film thickness • minimizes the effects of temperature and current density fluctuations during anodizing • increases the capacity of sulphuric acid anodizing processes as higher temperatures are possible.
