[1] Where powder is used, allow solution to set undisturbed 24 hours before use.
The small amount of precipitation which forms will not bother the coating
process.
[2] Alodine 1000L is a liquid concentrate. One gallon of concentrate is
equivalent to 1 ounce of Alodine 1000 powder.
[3] The pH may be lowered by additions of the Alodine until the top of the
concentration range is reached. Discard the solution when the pH reaches the
maximum value. Do not attempt control by adding acid.
NOTE: All gallons are U.S. gallons.

Material Preparation Instructions
1200 Add 3 ounces of powder to water for each gallon of final solution.
Stir well until the powder is dissolved. Disregard any small amount
of settled-out insoluble material. Allow to stand at least one hour
before use. A pH range of 1.50 to 1.90 is required and adjusted by
addition of nitric acid.
1200S Add 2 ounces of powder to water for each gallon of final solution.
Stir well until the powder is dissolved. Disregard any small amount
of settled-out insoluble material. Allow to stand at least one hour
before use.
1000 Add 0.4 ounce of powder to water for each gallon of final solution.
Stir well untilthe powder is dissolved. Disregard any small amount
of settle-out insoluble material. Allow to stand at least one hour
before use.
1000L Dilute 4 volumes of the Alodine 1000L with 6 volumes of water and
stir well to produce a final concentration of 0.4 ounce of Alodine
