Polyether Defoamer GP-330 is a non-ionic high-efficiency defoaming and foam-suppressing additive specially designed for water-based systems, featuring five core characteristics: rapid defoaming, long-lasting foam suppression, high-temperature resistance, strong chemical stability, and broad versatility.
Detailed Description
Polyether Defoamer GP-330, with the chemical name glycerol polypropylene ether (CAS: 68439-50-9), belongs to non-ionic surfactants. The product appears as a colorless to light yellow transparent viscous liquid with excellent water dispersibility and system compatibility. As a defoamer designed specifically for water-based systems, it can quickly eliminate existing foam within a very short time, rapidly restoring normal working conditions, while continuously exerting foam suppression effects in the system to effectively prevent foam regeneration and ensure production continuity.
The product exhibits excellent temperature resistance, maintaining stable defoaming activity under high-temperature conditions without easy decomposition or failure. Its chemical stability is equally outstanding, capable of withstanding acidic, alkaline, and hard water environments, and reliably functioning in complex systems. Additionally, GP-330 is compatible with various water-based resins, additives, and formulation systems, and is less prone to causing coating defects such as craters or fisheyes, which are highly valued in the paint and ink industries.
From a usage perspective, GP-330 is in liquid form, easy to measure and add, disperses uniformly, and does not easily stratify or sediment. It has low physiological activity, no known significant hazard classification, is classified as a non-dangerous substance, and exhibits low toxicity to aquatic organisms. However, direct discharge into the aquatic environment without treatment should still be avoided.

Application Recommendations
GP-330 is suitable for defoaming and foam suppression needs in various water-based systems. Recommended application areas include:
- Water-based Coatings and Adhesives – Rapidly breaks foam during dispersion, mixing, and application, reducing coating defects such as craters and pinholes, and improving surface appearance; eliminates foam during stirring and gluing to prevent adhesive gaps and strength reduction.
- Water-based Inks – Quickly defoams during high-speed printing, avoiding ink mist and mottling, maintaining image clarity and color vibrancy.
- Industrial Water Treatment – Suppresses foam generation in aeration and circulating water systems, reducing overflow risks and improving system efficiency.
- Textile Dyeing and Finishing – Provides long-lasting foam suppression under high-temperature and high-shear conditions, preventing color spots and streaks, ensuring uniform dyeing.
- Paper Manufacturing – Controls foam during pulping and papermaking processes, preventing paper defects and air spots, improving sheet formation and smoothness.
- Metalworking Fluids – Suppresses foam accumulation in cutting and grinding circulation systems, enhancing cooling and lubrication effects and machining precision.
- Industrial Cleaning – Reduces foaming tendency of cleaning agents, preventing overflow from tanks, ensuring cleaning power, and protecting equipment operation safety.
Precautions
- Operation Protection: It is recommended to wear chemical safety goggles and impermeable gloves (e.g., nitrile rubber or neoprene) during operation to avoid contact with eyes and skin.
- Storage Conditions: Store sealed in a cool, dry, and well-ventilated area. Recommended storage temperature is 5°C to 35°C. Avoid direct sunlight, freezing, and prolonged high-temperature storage.
- Emergency Measures: In case of eye contact, immediately flush with plenty of running water for at least 15 minutes and seek medical attention; in case of spillage, contain with inert absorbent materials (e.g., sand, vermiculite) and collect, avoiding wash water entering drains.
- Environmental Note: This product exhibits low toxicity to aquatic organisms, but direct discharge into the aquatic environment without treatment should still be avoided. Waste should be disposed of by qualified professional agencies.
