ICM_weblogo.gif (1693 bytes)

Type ........................... Silicone emulsion
Physical form ............ Liquid
Special Properties ..... High performance; effective in small concentrations; easily dispersed.
Primary use ............... Suppressing foam in systems processing non foods.

ICM AF 20 antifoam emulsion is a water-dilutable silicone material that can be
used to suppress foam in processing non-foods. It contains 20-percent active silicone
defoamer in a nonionic emulsion.

TYPICAL PROPERTIES:

Active Defoamer, percent ...........20

Specific Gravity at 77F (25C) .... 1.0

Color .......................... Cream White

pH ............................................. 7.5

Emulsifier ........................ Nonionic

Suitable Dilutent ................. Water

APPLICATIONS:

Although ICM AF 20 antifoam emulsion is primarily used to suppress foam in processing non-food products, it is also often used to suppress foam in various chemical processing applications. It is especially effective in certain latex emulsions.

Typical non-food processing applications include:

Fermentation
Paper coatings and sizes
Waste yeast tanks
Non-food washing solutions
Wastewater treatment systems

HOW TO USE:

ICM AF 20 antifoam emulsion should always be diluted with water or with
a portion of the foamer before addition to the system.

Concentration:

Although ICM AF 20 antifoam emulsion should be diluted before use,
concentrations (ppm) in the foamer are expressed in terms of the product as supplied.
Only 5 to 30 parts per million are normally required. As a starting point for evaluation work,
add enough diluted antifoam to give a concentration of 10 ppm.

Dilution:

First, stir or agitate ICM AF 20 antifoam emulsion before removing it from the shipping
container. Then follow these dilution steps:

1. Dilute the required amount of antifoam with 3 volumes of water or foamer. Slowly add
the water (or foamer), and stir gently until a uniform mixture is obtained.

2. Use the diluted antifoam within eight hours. Longer storage may cause the emulsion to
break and lose antifoam efficiency. If longer storage is necessary, stir the mixture frequently.

3. Add the diluted antifoam to the foaming system. Stir or agitate to insure complete
dispersion and effective foam control.

Amount Needed:

For specific applications, the required amount of ICM AF 20antifoam emulsion can be
determined by starting at 100 PPM concentration and increase/decreaseuntil performance
requirements are met.
