PASSIVE 8LD
Stainless Steel Passivation Solution
This process is required to restore the chromium oxide layer to stainless steel road tankers, ISO tanks, and IBC’s. This formulation is better suited for older and/or more stained tanks, especially when there is discoloration over the tank’s heating coils . See “Passivation FAQ.”
PASSIVE 8LD is an accepted scientific method used in stainless steel passivation, following ASTM-A967 recommendations. It is manufactured with nitric & hydrofluoric acids, in the exact percentages specified by the standard. It is ready-to-use, thereby minimizing material handling. PASSIVE 8LD restores chromium oxide dynamically so that the tank can load immediately after the process.
PRODUCT DESCRIPTION
Use PASSIVE 8LD for the restoration of the chromium oxide passive film on stainless steel road tankers, ISO tanks, and IBC’s. Also restores the chromium oxide passive film in AISI 300 Series Stainless Steel Vessels (304, 304L, 316, 316L, 316T, 321) in the process.
For best results apply with Fogging device, such as the John-Henry® Simplicity Fogger, which creates a 10 micron fog to deliver the chemical, thereby compensating for the high surface tension of nitric acid.
USES AND DIRECTIONS
Use PASSIVE 8LD for stainless steel ISO tanks, tankwagons, and IBC’s. Also restores the chromium oxide passive film in AISI 300 Series Stainless Steel Vessels (304, 304L, 316, 316L, 316T, 321) in the process.
Prior to application of PASSIVE 8LD, tank should be clean and free all residues. PASSIVE 8LD will not work when used as a cleaner.
Forty foot single compartment trailers as well as large IMO tanks require 10 gallons of PASSIVE 8LD. Two, three or four-compartment trailers require less per compartment, but the same ten gallons for the sum. After tank has been cleaned, remove presolve equipment and seal tank. PASSIVE 8LD application and standing time should not exceed 45 minutes.
