    AI Overview
    Silicone defoamer powder is a highly concentrated, free-flowing, solid antifoaming agent based on modified polysiloxane and silica technology. It rapidly eliminates and prevents foam in industrial applications, dry formulations (pesticides, cement), water treatment, and textile processing. It is known for its high efficiency at low concentrations, high-temperature resistance, and strong alkali resistance. 
    Key Features and Benefits 
    • High Performance: Provides rapid knockdown and long-lasting foam suppression in aqueous and non-aqueous systems.
    • Versatile Applications: Ideal for dry mix formulations like agrochemicals, detergents, and cement admixtures.
    • Stability: Excellent storage stability and容易 (easy) dispersibility in water.
    • Safety: Often considered inert, safe, and effective for food-related applications (under specific regulations). 
    Common Uses 
    • Dry Flowables & Powders: Wettable agrochemical powders, powdered cleaners, and cements.
    • Waste Water & Processing: Controls foaming in waste tanks, pulp and paper production, and industrial scrubbing systems.
    • Coating & Painting: Eliminates foaming in ink and paint applications. 
    Key Products & Types 
    • Magrabar® MD-20-S: A powdered silicone antifoam with a maltodextrin carrier used for dry formulations.
    • TIS-381: An organosilicone surfactant powder with high temperature resistance.
    • SILAF PDR: A free-flowing powder containing silicone antifoam, ideal for agrochemicals and concrete.
    • Silicone Emulsion Powders: Specialized powders that provide both defoaming and, in some cases, anti-sticking properties. 
    These products are often used to replace liquid defoamers in applications where water addition must be avoided.
