Polyether defoamer GP-330 (chemical name: glycerol polypropylene ether, CAS number: 68439-50-9) is a nonionic surfactant, appearing as a colorless to light yellow transparent viscous liquid. This product features rapid defoaming and long-lasting foam suppression as its core advantages, capable of quickly eliminating existing foam within a very short time and continuously preventing foam regeneration. It also exhibits excellent temperature resistance and chemical stability, reliably functioning in acidic, alkaline, and hard water environments. Its liquid form facilitates easy metering and addition, and it is highly compatible with various water-based resins, additives, and formulation systems, without easily causing defects such as craters or fish eyes in coatings.
GP-330 is a versatile defoaming agent designed for water-based systems, covering a wide range of applications from coatings and printing to industrial circulating water treatment. It is particularly suitable for processes requiring both fast defoaming speed and prolonged foam suppression.
| Industry | Typical Process Stage | Effect |
|---|---|---|
| Water-based Coatings | Dispersion, mixing, coating | Rapid bubble breaking, reducing coating craters and pinholes, improving surface quality |
| Adhesives | Stirring, application | Eliminate foam, prevent adhesive layer defects and strength reduction, ensure uniform bonding |
| Water-based Inks | High-speed printing | Quick deaeration, avoid ink misting and mottling, maintain image clarity and color saturation |
| Industrial Water Treatment | Aeration, circulating water systems | Suppress foam generation, reduce overflow risk, improve system efficiency |
| Textile Printing and Dyeing | High-temperature, high-shear dyeing processing | Long-lasting foam suppression, avoid color spots and stains, ensure fabric level dyeing |
| Papermaking | Pulping, papermaking | Control foam, prevent paper defects and air spots, improve sheet formation and smoothness |
| Metalworking Fluids | Cutting, grinding circulating systems | Suppress foam accumulation, enhance cooling and lubrication effects, improve machining precision |
| Industrial Cleaning | Cleaning bath solutions | Reduce cleaning agent foaming, avoid foam overflowing the tank, ensure cleaning power |
GP-330 is suitable for defoaming and foam suppression needs in various water-based systems. It is recommended to verify compatibility with the system and determine the optimal dosage through small-scale tests before use. Typically, it can be added during the material mixing stage or before the foam generation stage, allowing the system's own shear force to disperse it evenly. For high-temperature processes (e.g., textile printing and dyeing), this product maintains stable defoaming activity under high-temperature conditions without easy decomposition or failure, making it an ideal high-temperature defoaming choice.
