Good corrosion resistance
|Coating Type||Color||Thickness/um||SST/h||PCT/h||Working Temp/℃||Performance features|
|Blue Zn||Blue/White||5-10||≥48||–||＜160||Medium corrosion resistance performance|
|Color Zn||Multiple colors||5-10||≥72||–||＜160||Medium corrosion resistance performance|
|NICUNI||Silver white||10-30||≥72||≥96||＜200||High corrosion resistance, thermal resistance and moisture resistance|
|PVD Aluminium||Silver white||5-25||≥96||≥240||＜390||High corrosion resistance and adhesiveness|
|Phosphate||–||–||–||–||＜250||Low cost, low corrosion resistance performance|
|Epoxy||Black/Grey||10-30||≥480||≥96||＜180||High corrosion resistance and insulation performance|
|Multi-layer coating||–||–||≥1000||≥480||–||Excellent corrosion resistance performance|
This performance might vary according to different dimension of product.
Multi-layer coating is a combination of different type of coatings, and its color,thickness and working temperature might varies from different combinations.
