Corrosion Testing: Flash Rust Protection at pH ~3 to ~5.5
Procedure: Cold rolled steel panels were placed into each solution and allowed to soak for ~1 hour at room
temperature. The steel panels were removed and allowed to air dry without rinsing.
No rust forms on the panels if DeCORE AFCI-45 present.
