CHEMICAL & PHYSICAL PROPERTIES

Chemical composition ………………. a mix of surfactants,caustic soda, silicates and phosphates
Physical form…………………………….. white powder or off white in solution
Odor………………………………………….. faint aromatic
Bulk density ………………………………. 9.60 lbs/gallon
Hygroscopic tendency ……………….. positive
Foaming tendency …………………….. controlled
pH at working concentration ……… 13.2 at 6.0 oz/gal, 70 ºF

Trapping irritating or annoying vapors and/or mists is a added benefit for using Oakite 90. It will not trap ignitable gasses. Oakite 90 forms a controlled blanket of foam and because it does not contain soap, there is not a rinsing problem.

APPROVALS

Oakite 90 is approved for use as an alkaline steel cleaner (Materials bulletin 1005K); Alkaline magnesium cleaner (Materials bulletin 1282A) by Bell Helicopter, and an alkaline cleaner(BAC 5749) by Boeing.
Now recently approved for use by Lockheed Martin

APPLICATION

Oakite 90 is applied in the range of 45 to 90 g/L (6 to 12 oz/gal) of water, 82º to 93ºC (180º to 200 ºF) with reverse current of 5.4 to 10.8 A/dm2 (50 to 100 A/ft2) 6 to 9 volts. Time of application is normally not critical and may vary from 30 seconds to 2 minutes

Preparing Solutions: Fill tank to working level with cold water and slowly sprinkle in the required amount of Oakite 90, stirring well to avoid spattering. Then, heat solution to operate temperature. When making upkeep additions, let solution cool before introducing additional material. Do not add large amounts of dry powder to solution at any one time. Do not add to hot water or hot solution above 43º to 49 ºC (110º to 120 ºF)
