Property：
|
| 1. |
"Nai-Hsin，"the non-chromate method of metallic surface treatment adopt matellic Zn-Al flakes and special inorganic monomer as precursors. With high temperature proceeding(310-340 oC), it prevents the oxygen and moisture in the air and passivate the metallic surface with excellent corrosion-resistance. |
| 2. |
The coating treatment on finished goods be extremely thin only 6 to 15 um, but it demonstrates much better anticorrosive effect than electroplating and hot dip galvanizing methodes by its high temperature resistance and non-hydrogen embrittlement. |
| 3. |
The treated products with Nai-Hsin are complied with the limit of ROHS Standard of EU，without toxic heavy metal Cr(III) and Cr(VI). The United States and Japan also follow this standard. |
| 4. |
During this process of treatment，it won't be any wastewater and waste gas. It is the best method for environmental protection with powerful product competitiveness at the same time. |
| 5. |
The metallic products with Nai-Hsin are proved by 200 to 1000 hours for salt spraying test (ASTM-B117). |
| 6. |
This process could be implemented with spin-coating or spraying. |
Application：
|
| Screws, nuts, parts of automobile/motorcycle/bike etc, the accessories for bridge, civil engineering, cast iron, aluminum, and any products with corrosion-resistance. |
