mine if aluminum containers are suitable for use with a given
formula is, once again, to conduct corrosion tests. Corrosion tests
could be either a traditional storage stability test (static storage
test) or the shorter electrochemical corrosion test.
Next issue, we’ll continue with a discussion of Tin-Free-Steel
(TFS).
Pair O Docs has a state-of-the art electrochemical corrosion testing
laboratory; please contact me if you would like to know more
about our faster and predictive corrosion testing. You can also visit
our new website which has a short Vision Video that discusses all
our corrosion prevention and control services.
Please also contact me if you would like to a have our
Elements of Spray Package Corrosion short course taught at your
R&D facility. Thank you for reading Corrosion Corner and I’ll see
you in November. SPRAY
