Features Of Solvay Clearbreak DI 719 Surfactant

  1. Highly effective defoamer specifically engineered for demanding industrial water-based systems.

  2. Excellent compatibility with anionic, nonionic, and cationic formulations without compromising stability.

  3. Low-foaming profile enables rapid foam suppression and sustained antifoam performance under shear and elevated temperatures.

  4. Water-dispersible liquid form ensures easy handling, metering, and homogeneous incorporation into process streams.

  5. Compliant with REACH and meets key regulatory requirements for industrial use in non-food-contact applications.

Typical Applications Of Solvay Clearbreak DI 719 Surfactant

  1. Wastewater treatment plants for foam control in activated sludge and biological reactors.

  2. Industrial cleaning formulations including CIP (clean-in-place) and alkaline degreasers.

  3. Paper and board manufacturing—particularly in coating, sizing, and white water systems.

  4. Paints and coatings production to prevent foam during mixing, grinding, and filling operations.

  5. Textile processing auxiliaries, especially in dyeing and finishing baths where foam interferes with fabric wetting.
