a stable water-emulsion of methyl polysiloxane

Under normal use conditions, no physiological effects are known due to skin contact or inhalation of sprayed droplets. Not FDA-approved for use in food processing.

Quantity Required -- Method of Use

Quantity required for specific applications varies greatly; the range is from about 1 to 200 parts per million parts of foaming solution.
Normal Rangefrom 1 ppmto 200 ppm
Equivalent to1 oz:8000gal1 oz:40 gal

Normally, try at 1 oz:100 gallons of foaming solution; increase or decrease as needed.

Full-strength Defoam #100 may be added directly to foaming solution.

But for quicker dispersion in the solution, premix Defoam #100 with 10 parts water and add mixture to the foaming solution. Mixture may be added by pouring into the liquid or by spraying on the foam; spraying caused foam to disappear on contact. Premixed solutions must be shaken or stirred before use if allowed to stand over one hour.
