Surface Performance of Chrome-Free Anti-Fingerprint Zinc and Zn-Al-Mg Coated Steel

Abstract:

A principle investigation of the fingerprint resistance, alcohol resistance, solvent resistance, humidity resistance, high temperature resistant yellow degeneration and black tarnish resistance of pure Zinc and Zn-Al-Mg coating were performed in this study. To detect above surface performance and make some constructive suggestions, a series of simulations experiments and a surface performance evaluation system based on light color differentiation measurement instrument were designed. The results show that the two products both can meet the needs of users in above-mentioned surface performance, besides pure Zinc coated product has more advantages in this performance in comparison to Zn-Al-Mg coated product. Users should pay attention to clean the fingerprint regularly which attached to the surface of the steel plate during use and the protection with the exposed surfaces of the steel during shipping.
