Chrome-free,superior anti-corrosion metal surface treatment especially improve gas resistance further

 

NICOA can be called as the advanced ruspert treatment especially for improve gas resistance further.The 2nd layer in the ruspert treatment metallic zinc layer and special rustproof film which has good adhension replace chemical convension film.the film thickness is approximate 15μm that the no differential between part of smooth and adge,also improve the edge cover ability of screw thread and so on through new coating technology.as result chrome-free composite coating formed which has excellent gas resistance,such as SO2 and other anti-corrosion gas.
