Defoamer DEF32

Our DEFOAMER DEF32 is a high-performance, milky white oil-in-water emulsion specifically formulated for rapid and long-lasting foam control in a wide range of aqueous systems. Its core active ingredient is polydimethylsiloxane (silicone oil), combined with hydrophobic silica to enhance its defoaming efficiency. This ready-to-use emulsion is easy to handle and dilute, providing an economical and effective solution for combating problematic foam in industrial processes.

The main detailed uses of the product
  • Water Treatment
    Water Treatment

    Used for scale inhibition and corrosion control in industrial water systems.

  • Textile & Paper Processing
    Textile & Paper Processing

    Biodegradable wetting agent.

  • Agrochemicals
    Agrochemicals

    Plant hormone (phytohormone) that induces systemic acquired resistance (SAR). When applied to crops, it can activate the plants' own defense mechanisms, making them more resistant to pathogens, thus reducing the need for traditional pesticides.

  • Food Processing & Sanitation
    Food Processing & Sanitation

    - Surface Sanitizer: Used to disinfect equipment, pipelines, and food contact surfaces. - Food Bleaching: Employed in bleaching food items like starch, flour, sugar, and oil

  • Textile Treatment
    Textile Treatment

    Imparts anti-static and softness properties to synthetic fibers, enhancing comfort and processability in textiles.

Why Choose Our Defoamer DEF32?
