Aluminum Chromate Powder Coating Delay: Safe 24-Hour Rule

Summary for aluminum chromate powder coating delay Discussion

Delay between aluminum chromate and powder coating is the central question here: Senthil asks how long to wait after chromate treatment on aluminum before powder coating. The reply points to earlier site discussions on the same topic, noting that there are several opinions about the acceptable delay between chromate conversion coating and painting or powder coating. No single universal interval is given from the thread itself, but the answerer says that, in his view, following an in-house specification of 24 hours would be a safe choice. The advice is cautious rather than absolute, and it implies that plant standards or customer requirements should govern the timing when available. The thread therefore serves mainly as a practical pointer to prior discussion and a conservative rule of thumb from the named responder.
