Dispersing Agents

Dispersing agents are polymeric or surfactant-based additives that prevent the agglomeration of solid particles, keeping them uniformly suspended in a liquid carrier. For solid-based or compound defoamers (especially those containing hydrophobic silica, EBS wax, or fatty acid salts), dispersing agents are essential to maintain a homogeneous and effective formulation.

    FEATURES

     General Properties: Provide steric hindrance or electrostatic repulsion; available as liquid or powder forms with high molecular weights.
     Synergistic Role in Defoamers: Solid defoamer particles naturally tend to clump together or settle at the bottom of the container. Dispersing agents coat these particles, creating a repulsive barrier that keeps them finely and evenly dispersed within the carrier liquid.
     Performance Benefits:
    Prevents Settling and Agglomeration: Maintains long-term suspension stability, ensuring the defoamer remains uniform from the first drop to the last.
    Consistent Dosage: Ensures every dose contains the exact same ratio of active solids, preventing under-dosing or over-dosing.
    Prevents Equipment Blockage: Keeps solid particles finely milled and suspended, preventing them from clogging spray nozzles, filters, or dosing pumps.
