CARDITE #4PR
Rinse Additive for Pickled Steel

Promotes free rinsing and rapid drying. Prevents spots, stains and discoloration.

Inject into rinse water used after acid pickling. If multi-stage cascade rinsing is used, inject into next-to-last rinse stage. Since Cardite #4PR is a low-viscosity liquid, the feed rate can be accurately controlled by feeding into the rinse water through a metering pump or a venture injector. At usage levels, foam is not problem.

Recommended Use Dilution

0.5% solution
Equivalent to 0.64 oz/gal water = 1:199 water

Example: If rinse water inflow is 10 gallons per minute = 600 gallons per hour, inject Cardite #4PR at any of the following equivalent rates:

at3 gallons per hour,
or384 fluid ounces per hour,
or6.4 fluid ounces per minute,
or189 milliliters per minute.
