01 / Product brief

Faster Cycles, Uniform Coverage on Complex Geometries

Oxidising bath accelerator for phosphating baths. Removes hydrogen evolved during the phosphating reaction, preventing H₂ bubbles from blocking crystal growth sites. Reduces process time and improves coating uniformity and coverage on complex geometries and blind holes.

Maintains optimal Free Acid / Total Acid ratio through a full production shift, reducing bath correction frequency. Consistent oxidising potential produces uniform coating weight across a batch — critical for OEM specification compliance.
