ECOGREEN COLOR TONE

The regulation of the hexavalent chrome is shouted from the position of the global environment preservation recently by the RoHS designation and so on.
The metal surface treatment [ ECOGREEN ] of " Zero Chromium S process " high corrosion resistance was developed with the special organic acid and the treatment technology, and put to practical use as a system-ization in our company by the individual development.

Characteristics of ECOGREEN deposition film

Used chemical doesn't have danger and handling is easy.

A present plating line can be used as it.

Waste water treatment loads can decrease drastically because of the deposition film of
the Organic acid subject.

It is environment because of an Organic acid deposition film, and a human body is harmless.

Protection action is seen even if a deposition film is damaged because of an organic acid deposition film.
(Is similar to the self-repair action of Chromate deposition film)

A deposition film appearance can get an interference color with matt.

The corrosion resistance doesnft decline if the drying temperature is high. (To 150

)

It has flexibility because it is an Organic acid deposition film.
(Deposition thickness 0.2µ)

A low electric current plating part sample

Two part divides the 46F iron pipe lengthwise and a circumference is fixed by the adhesive tape after Zinc plating and took out 2 part, one side ECOGREEN treatment, the other side trivalent Chromate treatment.

The photograph of the upper left is ECOGREEN. Zinc was plated or wasn't plated on the pipe inside either ECOGREEN is treatment in the whole of the inside. The photograph of the bottom left is trivalent Chromate treatment. Have not Chromate treatment place it doesn't Zinc plating.
