The regulation of cadmium and lead and the hexavalent chrome is shouted from the position of the global environment preservation recently by the RoHS designation and so on. "NIPRON -930" made lead. cadmium as a stable chemical used for the electroless Nickel completely free, and corrosion resistance improved remarkably, too.
It is the latest product for the environment which meets the request of the green procurement [ RoHS designation,ELV designation, WEEE designation ]

Characteristics of "NIPRON-930"

Lead free.

Non hexavalent Chromate treatment, high corrosion resistance deposition film.

Corrosion of a deposition film was improved remarkably.

Deposition speed 14 - 18µm/H are continued steadily in a long time.

Cost is reduced and can be adjusted with sodium hydroxide.

By raising the dissolution of the hydroxide,
rough and the growth of the pit were improved.
