Phosphate Coating Weights & Powder Thickness
How much will the corrosion performance of a component be affected if the coating weight is reduced from 120 to 80 GSM?
Q. I understand that coating weights and film thickness can have an impact on corrosion performance of powder coated steel. My question is: how much will the corrosion performance of a component be affected if the coating weight is reduced from 120 to 80 GSM? Similarly, how will increasing the DFT from 50 to 70 or decreasing it from 70 to 50? The substrate for both these scenarios is galvanized steel. J.S.
Simply heating up the substrate does not cure the coating. There are many variables to consider when choosing the best cure oven for your application...
Infrared cure is gaining increased attention from coaters as a result of shorter cure cycles and the possibility of smaller floor space requirements when compared to convection oven curing.
Powder coating is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe because of its lack of volatile organic compounds.
