Phos Kleen # 13

Phos Kleen #13 is a mildly acidic liquid compound for one step cleaning and phosphating iron and steel surfaces.  Phos Kleen #13 may also be used to prepare aluminum and galvanized surfaces for painting.  It can be used as a pretreatment for painting and produces an amorphous iron phosphate coating on steel that will be blue to gold iridescent in color.  Phos Kleen #13 is generally used in spray operations but can be used in immersion operations.

Use Instructions
Spray/Immersion
:  Phos Kleen #13 is generally used in three stage spray washers.  It can be used in four stage units as well as in washers where the phosphate is built up in the first two stages.  Normal operating range is 1 to 3 minutes at 100 - 140°F.  In spray applications where the work is extremely dirty or in immersion applications, these stages should be preceded by alkaline cleaning and a rinse.  The complete process for the most effective application of Phos Kleen #13 will generally consist of the following steps:
1.  Phos Kleen #13 Solution
2.  Cold Water Rinse
3.  Sealing Rinse (optional, depending on part end-use requirements)
Cold Water Rinsing:  It is important to have good cold water rinsing after the cleaner/phosphate treatment.  The flow of cold water through the rinse should be regulated with the rate of production so that the main body of the rinse will not become excessively contaminated.  Fresh water is added most efficiently to a rinse tank through a fresh water riser at the end of the rinse stage.
Rinsing with a Seal:  Following the cold water rinse, a sealing rinse may be applied to the parts if increased corrosion protection is desired.  Your Spray Chem Representative will provide assistance with the selection of the proper seal for each application.
Drying:  Following the rinse, the work should be dried as quickly as possible.  Usually an indirect fired oven is used.  If pockets or cavities which retain moisture are present in the parts, forced air drying should also be used.
Make-Up:  Partially fill tanks with water.  For each 100 gallons of solution add 3 -4 gallons of Phos Kleen #13.  Add additional water until the working level is reached.  Mix thoroughly and heat to 100°F.  Check the pH of the bath and adjust if necessary to achieve a pH between 4.0- 5.0.  Phosphoric acid is used to lower pH; sodium hydroxide is used to raise pH.  Use small additions of pH adjustment materials and mix thoroughly when adding.
Bath Operation and Control:

Titration
1.  Fill the test tube to the 10ml mark with the solution to be tested.
2.  Add 5 drops of Phenolphthalein Indicator.  Swirl to mix.
3.  Add 2.0 N Sodium Hydroxide drop wise, swirling to mix, until the color changes to red.
4.  Record the number of drops.
Number of drops x 0.24 = Percent by volume of Phos Kleen #13.
