Instructions for use

Product features

Free of hexavalent chromium, free of silver and other harmful metals Green products, passed SGS product testing and certification, comply with ROHS, ELV regulations, suitable for export orders in Europe and America.

		Obtain a deep black uniform passivation Film The film is dense and strong, with good anti-collision and anti-scratch ability; suitable for auto parts products with hardness and wear resistance requirements.

Excellent corrosion Resistance The nano-sealing agent is added to the product, which has good anti-rust ability. When the thickness of the zinc layer is 5-8 microns, it can resist NSS ≥ 72 hours, which can meet the functional requirements of the upper-grade hardware products.

		Passive film has high temperature resistance Avoids the defect that the passivation film has reduced corrosion resistance after heating.

Long-term storage, the passivation film is not easy to return hexavalent chromium Easily pass the boil test and SGS test, the passivated product is not easy to produce hexavalent chromium after long-term storage, avoiding the risk of customer return.

		High tolerance of Impurities The tolerance of metal impurities in the passivation working fluid is high, zinc> 7 g, iron> 100 mg, which can reduce the time of shutdown and the loss of passivation agent, saving costs.
