Corrosion Protection Provided by EonCoat Continues to Improve
Several of you have chastised me recently for not keeping you up to speed on our progress. Guilty as charged. I’ll try to make it up to you.
The best thing about running this company is that at least twice a week someone comes to my office with a big smile to show me what new thing we can now do.
Over the next few blogs I’ll talk about several of them, but today’s post is about our understanding of corrosion protection.
We have been saying for some time now that it is the magnesium iron phosphate layer that is covalently bonded to the steel which is the primary method of protection. The magnesium iron phosphate is a very thin alloyed layer.
Recently we’ve learned a great deal about how to optimize the formulation of that layer. There are three primary variables that affect the alloyed layer and thus the coating performance. You will forgive me if we don’t list those here. But this means we must evaluate every additive for its impact on those three variables.
The good news is we are getting very good at understanding what is going to happen in the corrosion tests. Those tests have gotten significantly more reliable lately and thanks go to two groups for pushing us to make that happen:
Joe Taylor at Thomas Built Buses got us using MgCl in a salt fog and cyclic chambers because they needed to understand service on salted roads in the winter. Eight months ago EonCoat did not perform well in a MgCl fog (a brutal test) — today the performance is absolute protection.
Thanks also goes to Mr. Y. H. Yoo of Seoul, Korea who enlisted the services of Dr. Ahn to start electrochemical testing of EonCoat samples. Electrochemical testing is the gold standard for corrosion testing. It will measure results to a numerical value in a very short time frame and it is incredibly accurate. We have since purchased our own electrochemical testing equipment and this has further refined our understanding of how to optimize the EonCoat formula.
We are getting close to permanent corrosion protection on carbon steels.
Next time we will talk about color, hydrophobicity and a bunch of things the paint guys at the Chevron Pascagoula plant taught us were advantages to using EonCoat that we had not even considered.
