1500 Add 8 fluid ounces of Alodine 1500 to water for each gallon of final
solution. Stir to get a uniform mixture.
NOTE: All gallons are U.S. gallons.
When a water-break free surface cannot be obtained, Ridosol 501 wetting agent
(same source as Alodine) may be added to the solution. Add 0.10 to 0.50% by
volume, i.e. 0.128 to 0.64 fluid ounces per gallon.

GENERAL INFORMATION STANDARD TREATMENT METHODS
Material Variable Make-Up [1] Control
Iridite 14 Concentration pH Temperature 2.8 oz/ gal 2.7 to 3.3 oz/gal 1.0 to 1.7 [2] Room temp to 95°F
Iridite 14-2 Concentration pH Temperature 1.45 oz/gal 1.25 to 2.25 oz/ gal 1.1 to 16 [2]
Room temp to 95°F
[1] After make-up, allow the solution to set undisturbed for 24 hours before
using. The small amount of precipitate which forms will not bother the
coating process.
[2] Adjust the pH with nitric acid until a distinctly yellow adherent film is
obtained within the 5 minute immersion time on bare 2024 aluminum alloy.
