Use of NRP as a corrosion protective coating


In order to protect space heaters, with steel heating elements, from corrosion during storage, I have found a product made by Chemetall Oakite, called NRP.

Does anybody have experience with this product?

What I am looking for is info about possible safety hazards connected to this product "in the long run".

It is preferable to discuss technologies here than to discuss one particular solution from one vendor. Can you give us a hint what kind of technology we're talking about here?

Oakite NRP is a sodium nitrite based product used as a rust inhibitor. It can also be used in Zinc Phosphate Processes as an accelerator. My recommendation is to call Oakite's Health and Safety Dept. to request an MSDS. The MSDS, among other information, will advise of any short and long term safety concerns. You can call them and request the MSDS for NRP be faxed or mailed to you.

In response to Mr. Mooney's search, NRP is not listed on the website along with many other of our products. The products listed on the website reflect the top percentile of commonly used products. However, there is a direct e-mail request on the website where this question can be asked.
