FREICLEAN 10M is a liquid, alkaline, heavy duty cleaner for steel. The cleaner may be used for spray or immersion applications. FREICLEAN 10M is designed to remove phosphate and lubricant soils from steel work when exceptionally oily soils are present. Oily soils may be skimmed from the surface of the cleaning solution and stearate lubricant soils will not gel in the cleaning solution at ambient temperatures.
FREICLEAN 10M is a liquid, alkaline, heavy duty cleaner for steel. The cleaner may be used for spray or immersion applications. FREICLEAN 10M is designed to remove phosphate and lubricant soils from steel work when exceptionally oily soils are present.
FREICLEAN 10M may be used at concentrations of 5 – 10 % by volume, with operating temperatures of 150°-200°F. The normal processing t ime is 30 -90 seconds for spray applications and 3 – 10 minutes for immersion applications. For optimum removal of heavy phosphate coatings, a concentration of 10% by volume at 190°F with imme rsion time of 5 minutes or more is recommended.
The FREICLEAN 10M solution may be monitored by titration of the free alkali as follows:
Pipet a 2 mL sample of the FREICLEAN 10M solution into a suitable beaker or Erlenmeyer flask and add 4 drops of Indicating Solution 3 (Phenolphthalein). Titrate the pink solution with Testing Solution 20 (0.1N H2SO4) until the pink is just removed from the solution.
A FREICLEAN 10M solution prepared at 10% by volume will have a titration reading of
approximately 16.8 points Testing Solution 20. Addition of 6.0 gals (70 lbs) of FREICLEAN 10M per 1000 gals will raise the titration by 1 point.
FREICLEAN 10M weighs 11.7 lbs/gal. and has a specific gravity of 1.40.
CAUTION: This material is strongly alkaline and may cause burns to skin and eyes.
