Summary for one-step iron phosphatize Discussion
One-step iron phosphatize is the key question here: Dale Burford asked whether there is a single chemical that can both clean and phosphatize steel with some rust on it. The reply from Hi, KY Chek says a robust true one-step iron phosphatize is probably not practical. He explains that many shops use a 3-step iron phosphate process as the realistic minimum, even though it is less effective than a 7-step zinc phosphate system. He cautions that combining an alkaline degreaser, an acid rust remover, and a properly balanced phosphate step into one bath is not a workable shortcut. The answer also notes that alternate brands of phosphating chemicals may be available through advertisers, but the forum does not provide competitor distributorship information.
Q. I’m looking for a one-step iron phosphatizing chemical. It has to clean and phosphatize steel that may have a bit of rust on it. Am I looking for the impossible?

A. Hi, Dale. I don’t think a robust 1-step iron phosphatize is possible.
People often use a 3-step iron phosphate for practical reasons even if not as good as the 7-step zinc phosphate — just as they often eat 3-course dinners rather than a more satisfying 7-course one.
But I think 3 steps is the realistic minimum, and trying to combine an alkaline-based degreaser with an acid-based rust remover, with a properly balanced iron phosphate step is a bit like trying to use the clam chowder as the gravy for the meat loaf and substituting a scoop of strawberry ice cream for the mashed potatoes 🙂

Ed. note: This RFQ is outdated, but technical replies are welcome, and readers are encouraged to post their own RFQs. But no public commercial suggestions please ( huh? why?).
Hi, KY Chek.
I’m sure we will be able to help you locate alternate brands of phosphating chemicals if you wish; hopefully our advertisers are already reaching out to you. But this forum is made possible by our supporting advertisers and we really can’t ask them to bear the costs of maintaining distributorship information for their competitors’ products on these pages 🙂
