    High efficient Silicone defoamers IOTA C545


    C545 is a silicone antifoam emulsion based on BSI new generation high efficient silicone compound. It is recommended for the prevention, control or elimination of foam in aqueous systems, especially for metal working fluids and Agro application.


    1.         Easy dispersion in aqueous media.

    2.         Homogeneous and stable under wide PH and temperature range.

    3.         High antifoam efficiency in many applications, especially pulp black liquor.

    4.         High defoaming performance both at room temperature, middle and high temperature

    Examples of applications:

    IOTA C545 can be used in many industries such as:

    1.         Metal working fluids: in formulation or on site use

    2.         Agro chemicals: tank mix or in-can application

    3.         Cleaning: circuit wafer, wine bottle

    4.         Chemicals: distillation, extraction, filtration.

    5.         Oil-industry: extraction, butadiene process, amine-sweetening units.

    6.         Waste-water treatment: neutralization and biological step, outlet.


    1.      AppearanceMilky homogeneous liquid

    2.      Colorwhite

    3.      Odorweak

    4.      Dry content, approx. (%)73

    5.      Specific gravity at 25°C, approx.1.0

    6.      PH, approx.7

    7.      Viscosity 25°C, approx. (cps)2000

    8.      Emulsifier typeNon-ionic

    9.      Thinner: Water


    IOTA C545 can be pre-diluted before using, either with cool soft or deionised water for a use within 24 hours, In this case, the water is added to the antifoam slowly with slight stirring (do not use high shear mixers).

    IOTA C545 need fully dispersed in aqueous system to ensure best performance.

    IOTA C545 need mix prior to use.


    IOTA C545 is delivered in 25kg pail, 200kg durm.

    Storage and Shelf Life:

    When stored in its original unopened packaging at a temperature of between +2°C and +35°C, IOTA C545 may be used for up to 9 months from its date of manufacture (expiry date).

    After this date, IOTA SILICONE OIL no longer guarantees that the product meets the sales specifications.
