    1. Antifoam L-30 is a nonionic emulsifier

      How To Use

      Antifoam L-30 Emulsion works effectively in very low concentrations. One to 100 parts of active silicone per million parts foamer are sufficient to eliminate most foams. Begin trials at higher use levels (50 ppm active silicone), then work down to the level of foam control desired.

      The following are parts per million equivalents:
      To Yield 50 PPM Antifoam

      10.9 ounces mixed into 500 gallons
      22.0 ounces mixed into 1,000 gallons
      55.1 ounces mixed into 2,500 gallons
      16.5 quarts mixed into 25,000 gallons

      Adding the Antifoam
      To produce optimal foam control, it is necessary to have the antifoam completely dispersed in the foaming medium. Follow these steps to achieve complete dispersion:
      1. Agitate product prior to use.
      2. Predilute with 3 to 10 parts of cool water to aid in dispersion. Add the antifoam to the water with slow mixing. Prediluted material should be used immediately.
      If the system can provide adequate agitation to disperse the antifoam, the antifoam emulsion may be added directly without predilution being necessary.
      3. Add the diluted antifoam prior to the point where foaming occurs within the system, if possible.

      This product will freeze at or below 0°C (32°F). If frozen, Antifoam L-30 Emulsion can be thawed and used without loss of efficiency. Agitation may be required. Avoid storage conditions above 49°C (120°F).
