Metal Finishing Issue "Summertime is Corrosion Time"


Metal Finishing Issue "Summertime is Corrosion Time"

This is great news for air conditioning salesmen but metal finishers and their customers need to bring their "A" game when tackling corrosion resistance at this time of year. Care needs to be taken in the proper rust prevention and packaging necessary to get parts into our capable hands. Once we receive your parts we need to focus on the weather and how that weather affects corrosion before, during and after the finishing of your parts. Corrosion sensitive products need extra TLC at this time of year when applying Chemfilms, Dow processes, NH35, TCP and other various processes. We have the expertise to get the job done. We've attached 2 lists, one with suggestions for you our fabulous customers and a list that we follow that helps us through the summer/corrosion months at Saporito Finishing Company.
