Features Of Solvay Clearbreak PG 929 Surfactant

  1. Highly effective defoamer specifically engineered for challenging polyglycol-based systems.

  2. Non-silicone formulation ensures compatibility with sensitive analytical and process equipment.

  3. Excellent thermal and chemical stability across a broad pH range (pH 2–12).

  4. Low dosage efficiency — delivers robust foam control at concentrations as low as 0.05–0.3 wt%.

  5. Readily dispersible in water and glycol-rich media without pre-dilution or high-shear mixing.

Typical Applications Of Solvay Clearbreak PG 929 Surfactant

  1. Defoaming in industrial cleaning formulations containing propylene glycol or ethylene glycol.

  2. Foam suppression in heat transfer fluids and glycol-based coolant concentrates.

  3. Antifoam agent in metalworking fluid concentrates and soluble oil emulsions.

  4. Process aid in pharmaceutical manufacturing where silicone-free defoaming is required.

  5. Stabilization of glycol-based antifreeze and de-icing fluid production lines.
