Polyether Defoamer GP-330 is a nonionic surfactant based on polyoxypropylene ether with glycerol as the initiator, specifically designed as an efficient defoaming and foam suppression additive for water-based systems.
Detailed Description
Polyether Defoamer GP-330, with the chemical name Glycerol Polypropylene Ether (CAS: 68439-50-9), also known as C12-14 Alcohol Polyoxyethylene Polyoxypropylene Ether or Fatty Alcohol Polyether. The product appears as a colorless to light yellow transparent viscous liquid, belonging to nonionic surfactants, and exhibits good water dispersibility and system compatibility.
The core performance of this product lies in rapid defoaming and long-lasting foam suppression, capable of quickly eliminating existing foam within a very short time and continuously preventing foam regeneration in the system. It also possesses excellent temperature resistance, maintaining stable defoaming activity under high-temperature conditions without easy decomposition or failure. It has strong chemical stability, tolerating acidic, alkaline, and hard water environments.
The product has wide versatility, compatible with various water-based resins, additives, and formulation systems, and is less likely to cause coating defects such as craters or fish eyes. Its liquid form facilitates convenient measurement and addition, ensuring uniform dispersion without easy delamination or sedimentation.

- Water-based Coatings – Rapid foam breaking during dispersion, mixing, and coating processes, reducing craters and pinholes in the film, and improving surface quality.
- Adhesives – Eliminating foam during stirring and application, preventing adhesive layer defects and strength reduction.
- Water-based Inks – Quick defoaming during high-speed printing, avoiding ink misting and mottling, maintaining image clarity.
- Industrial Water Treatment – Suppressing foam in aeration and circulating water processes, reducing overflow risks.
- Textile Dyeing and Finishing – Long-lasting foam suppression under high temperature and high shear conditions, ensuring even dyeing of fabrics.
- Papermaking Process – Controlling foam during pulping and paper forming, improving sheet formation and smoothness.
- Metalworking Fluids – Inhibiting foam accumulation in cutting and grinding circulating systems, enhancing cooling and lubrication effects.
- Industrial Cleaning – Reducing foam generation in cleaning agents, preventing overflow from tanks.
Precautions
- This product is non-hazardous, physiologically inert, with no known significant hazard classifications.
- It is recommended to wear chemical safety goggles and impermeable gloves during operation, avoiding prolonged direct contact.
- Recommended storage temperature is 5°C to 35°C, sealed in a cool, dry, well-ventilated area, avoiding freezing and long-term high-temperature exposure.
- Avoid direct discharge into water bodies without treatment; waste should be disposed of by qualified agencies.
- When fumes are generated during high-temperature processing, ensure ventilation and wear appropriate respiratory protection.
