Product Description
The high‑corrosion‑resistant trivalent chromium passivation film for aluminum alloys, formulated with SanYong Company’s additive grade SY‑323, is a trivalent chromium chemical conversion coating additive designed for aluminum alloys and cast aluminum. After treatment, it yields a chemical conversion coating with exceptionally superior corrosion resistance—exceeding 720 hours in the neutral salt spray test—and outperforms both hexavalent chromium‑based and chromate‑phosphating coatings. This product is suitable not only as a pre‑coating pretreatment for aluminum and cast aluminum but can also serve as the final finish layer.
