PREPARING FOR APPLICATION
To enjoy the full benefits from using SOLUCOAT 5039 SPECIAL, the spray washing machine must be properly conditioned prior to application.
If the washer is new, circulate a 1/4 to 1/2 of 1% solution of the material through all stages for two to three hours, maintaining a temperature between 21 degrees and 38 degrees C (70 degrees and 100 degrees F). Then, dump the conditioning solution and recharge the machine with SOLUCOAT 5039 SPECIAL for the production run.
If the washer was previously charged with alkaline solutions, flush unit thoroughly with water, then circulate a 2 to 5% solution of RUSTKLEEN 5076 for about one hour. Rinse and follow procedure for conditioning new machine.
SOLUCOAT 5039 SPECIAL is used at 2 - 3% by volume with water at 1200 - 1300 F (do not operate over 170 degrees F).
If the machine was previously charged with acidic or solvent solutions, rinse unit thoroughly, then follow procedure for conditioning new machine.
Remove any rust or scale in the machine with RUSTKLEEN 5076, applied at 5 to 10% by volume. Rinse, then follow procedure for conditioning new machine.
If washer was previously used for iron or zinc phosphating, clean with a 3 to 5% solution of RUSTKLEEN 5081 at 71oC (160 degrees F), circulated three hours. Follow with rinse, adding enough RUSTKLEEN 5076 to obtain a neutral pH. Then, follow procedure for conditioning a new machine.
Before starting the operation, make sure all of the machine's spray jets and nozzles are in good working condition.
APPLICATION OF SOLUCOAT 5039 SPECIAL
For normal cleaning/conditioning with the phosphating material, a simple 3-stage procedure is followed in the pressure spray washer or vat. The normal working temperature range is from 21o
to 49 degrees C (70 degrees to 120 degrees F). The pH at working concentrations ranges from 4.0 to 5.0 with an optimum of 4.0. Where increased detergency is desired, SOLUKLEEN ENHANCER may be added up to 1/2% by volume of the working solution. Processing in SOLUCOAT 5039 SPECIAL should always be followed by a fresh water rinse to remove unreacted chemical and any contaminants loosened in cleaning.
For the final acidified rinse in the third stage, SOLUCOAT 5038 or SOLUCOAT NC Rinse (non-chromic) is recommended to improve the corrosion resistance of the phosphate coating.
Stainless steel 316 or 304 ELC holding tanks and heating coils are preferred but ordinary steel or black iron equipment may be used. Ask your local Working Solutions' Technical Sales Representative for specific recommendations.
