Hi,

In a supply chain mix-up, the supplier delivered a high temp CUI primer instead of a silica-zinc primer. The lead times to get the correct coating is eight weeks while the equipment is scheduled to ship out in a week. Both primers are rated for 1000F while actual application will see a maximum of 120F on the coast in tropical environment. The device is a part of a fuel feed system that does not need insulation. Would both coatings provide similar resistance to corrosion?

Thank you.
