Silicone Antifoam SF-40M

SF-40M stands out as an exceptionally robust antifoam. This concentrated formula utilizes one of our most elastic polymers, dispersed in water to tackle the most difficult foaming issues. Crosslinked silicone has a unique structure compared to linear silicones. Simple antifoams produced from linear silicones are prone to degradation under high and low pH and are sensitive to temperature changes. Crosslinking provides a 3-dimensional network of silicone polymer that becomes highly viscous and elastic. However, excessive crosslinking creates an insoluble and emulsifiable rubber. SF-40M features a crosslinked polymer, which SIXIN has optimized to maximize longevity and resistance to degradation. The emulsification package tailored for this highly crosslinked formulation makes SF-40M less easily modifiable.

    FEATURES

    The substance components of the antifoam do not contain the substances listed in the SVHC list of the REACH Regulation.
    Antifoaming agent component does not contain NP, APEO.
    Fast defoaming speed in application system (normal temperature -80 ℃).
    Good stability in alkaline environment (pH 8.0-11.0)

    HOW TO USE

    SIXIN® SF-40M Antifoam can be diluted with thickening water. In the process of dilution, the speed of stirring is between 30 to 60 rpm and the time of stirring is recommended for no more than 10 minutes. Please request SIXIN for the specific dilution method. The company accepts no responsibility for any loss which may be incurred by the customer as a result of incorrect usage.
    It is suggested that the product is added in a place where the antifoam can disperse easily.

    PACKAGE AND STORAGE

    The product is available in 25kg, 120kg and 1000kg plastic buckets; sizes can be customized according to special requirements. This product can be stored as a normal chemical, away from heat sources and direct sunlight. No exposure to rain. Keep away from flame. Don’t add acid, alkali, salt and other corrosive substances to this product.  Ensure the container is sealed after using. If this product begins to stratify after long storage, stir it evenly at 30 to 60 rpm. This product may freeze under 0℃ (32℉); if this happens, stir well after defrosting the antifoam at a rate of 30 to 60 rpm. In these cases, stirring will not affect the performance of the product if carried out at the recommended speed. When stored between 5 and 40℃ (41-104℉) in the original unopened containers, the product is usable 9 months from the date of manufacture.
