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.
Question: What methods are available for removing cured powder coatings, and what are the pros and cons of these methods?
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
Question: I’ve been told that a powder coated part cannot be “touched-up.” I have some patio furniture that I had powder coated and the powder coating shop that did the work for me stripped the threads in holes used to rack the part.
