FREIBOND D37 is a high quality low temperature iron phosphate coating chemistry for mixed metals applied by spray or immersion. FREIBOND D37 is designed to both clean the substrate surface and simultaneously impart a uniform coating excellent for bonding paint. The unique surfactant package provides superior cleaning performance, is very low foaming, and floats oils to the surface for easy removal. FREIBOND D37 may also be used by immersion but at double the recommended
concentration.

Stainless steel, mild steel, and high temperature acid resistant plastics are suitable for processing equipment. Utilizing 300 series stainless steel equipment will significantly increase the service life of the equipment. Full cone spray nozzles, such as Spraying Systems WhirlJet® nozzles, are normally used in spray applications to ensure uniform application of FREIBOND D37. Spray pressures should be maintained at 15 psig for optimum coating. Spray pressure above 20 psig will create inconsistencies and voids in the iron phosphate coating.

Utilization of deionized or reverse osmosis water in the system will reduce both chemical
consumption and sludge generation. Application equipment should be cleaned or a regular maintenance cycle with PICKLE 2 to remove sludge and scale deposits that may interfere with application and subsequent performance.

To charge the tank, fill to the three-quarter level with water and for each 1000 gallons of working
solution; add 30 to 60 gallons of FREIBOND D37 and the appropriate amount of NEUTRALIZER 35

Amount of NEUTRALIZER 35 required on a fresh buildup:
Gallons of FREIBOND D37used X 0.074 = Gallon of NEUTRALIZER 35

Bring the tank up to the working level with water and heat to the operating temperature, from 110oF –150oF. Once the optimum temperature has been determined, it should be maintained within ±5oF. A processing bath built up according to these recommendations will result in 6.0 – 12.0 points of Total Acid and a pH adjustment value of 0.0 – 0.4.

The typical process sequence for Freibond D37 application consists of the following steps:

1. FREIBOND D37 treatment (one or two stages)
2. Water Rinse
3. FREICON post treatment seal
4. Deionized water rinse
5. Drying
