Heavy Duty Alkaline Low Foaming Degreaser - Freiborne Industries, Inc Heavy Duty Alkaline Low Foaming Degreaser - Freiborne Industries, Inc

Product Type: Freiclean 209LF
   

Freiclean 209LF is a liquid, alkaline, medium to heavy duty, low foaming spray cleaner designed to remove oils and lubricant soils from steel. Freiclean 209LF is potassium based for easier rinsing resulting in less downstream contamination of subsequent processes.  Freiclean 209LF is effective where exceptionally oily soils are present.  Oily soils may be skimmed from the surface of the cleaning solution.  Freiclean 209LF is typically used for cleaning steel substrates in general parts washing applications and prior to conversion coatings and paint application.

Freiclean 209LF may be used at concentrations of 2 – 15 % by volume, with operating temperatures of 110°- 160°F depending on the severity and types of soils being removed. Normal processing time is 30 – 120 seconds for spray applications.  Typical operating parameters are listed below.  Effective operating ranges can vary widely depending on the soils present on the workpiece.  Consult your Freiborne Representative to help determine what operating parameters would be suit your operation.

 

Typical Spray Application Operating Parameters
Soil Load Concentration (% v/v) Temperature (°F)
Light 2 – 4 120 – 130
Medium 3 – 5 120 – 140
Heavy 5 – 10 130 – 160

Free Alkalinity Titration (Preferred Method):

The Freiclean 209LF solution may be monitored by titration of the free alkali as follows:

  1. Pipet a 5 mL sample of the Freiclean 209LF solution into a suitable beaker or Erlenmeyer flask
  2. Add 5 drops of Indicating Solution 3 (Phenolphthalein) (optional: add 50 mls of distilled, deionized, or reverse osmosis water)
  3. Titrate the pink solution with Testing Solution 20 (0.1N H2SO4) until the pink is just removed from the solution.
  4. Record the mls of Testing Solution 20 used as Free Alkali Points (save this solution and do not zero the buret if you plan on testing the total alkalinity).
  5. Calculate the Concentration by volume using the following equation:

Freiclean 209LF % v/v = (Free Alkali Points) x (0.833)

Addition of 8 gallons (76 lbs) of FREICLEAN 209LF per 1000 gals will raise the free alkalinity by 1 point.
