Description
SKU: 6000037 Parquench 90 – 5 Gallon Pail (Water Based Quenchant)
SKU: 6000037 Parquench 90 is a unique water based polymer quenchant. It is far superior to oil in its safety and environmental characteristics. Unlike polyalkylene glycols, PARQUENCH® 90 is completely water soluble at all concentrations and temperatures. It is non-flammable, non-toxic and provides desirable cooling characteristics, more reliable control in use, minimal environmental impact, and better economy.
PARQUENCH® 90 can provide cooling rates at all stages of quenching that approximate those exhibited by fast quench oils. Consequently, those conditions necessary for achieving maximum hardness in steel with minimum distortion or cracking can be realized.
PARQUENCH® 90 is widely used for quenching forgings in open tanks. It can also be used in continuous furnaces.

CONCENTRATION CONTROL:
Shell Cup Test Method (Shell Cup #2)
1. Submerge the cup in the 80°F sediment and air free solution. Allow approximately 30 seconds for the cup to attain sample temperature.
2. Lift the cup vertically out of the solution, starting the stopwatch as the bottom of the cup breaks the surface.
3. Record the time required for the cup to empty, stopping the watch when the stream first breaks.
4. Read concentration from the plot of time (seconds) versus percent by volume concentration.
CORROSION CONTROL:
If for any reason the existing corrosion inhibitor in the quenchant does not provide adequate protection, the addition of a small amount of RUST INHIBITOR SQ will reinforce the anti-corrosion activity, without interfering with the quenching mechanism of the polymer solution.
RUST INHIBITOR SQ
This inhibitor is solid and readily soluble in warm water. It is added to the quenching solution at a concentration of .1 – .5% (by weight) to provide a working pH of greater than 8.
