Polyether defoamer GP-330 (CAS number: 68439-50-9), chemical name glycerol polypropylene ether, also known as C12-14 alcohol polyoxyethylene polyoxypropylene ether or fatty alcohol polyether, is a nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. The product appears as a colorless to light yellow transparent viscous liquid, with good water dispersibility and system compatibility, allowing it to evenly disperse in water-based systems without easy layering or sedimentation.
The core advantages of this product are rapid defoaming and long-lasting foam suppression - it can quickly break existing foam within a very short time and continuously exert foam-suppressing effects in the system, effectively preventing foam regeneration. Additionally, it has excellent temperature resistance, maintaining stable defoaming activity under high-temperature conditions without easy decomposition or loss of effectiveness; strong chemical stability, capable of withstanding acidic, alkaline, and hard water environments, ensuring reliable performance in complex systems. Furthermore, GP-330 has wide versatility, being compatible with various water-based resins, additives, and formulation systems, without easily causing coating defects such as craters or fish eyes.
As a liquid form defoamer, GP-330 is convenient to use, easy to measure and add, making it an ideal choice for improving efficiency and product quality in water-based system production processes.
Based on existing product database information, specific physicochemical parameters of GP-330 (such as hydroxyl value, HLB value, cloud point, molecular weight, etc.) currently have no detailed numerical records.

GP-330 is specifically designed for water-based systems. Typical application areas and recommendations are as follows:
Coatings and Inks Industry: Used for rapid foam breaking during dispersion, mixing, and coating processes of water-based coatings to reduce coating defects such as craters and pinholes; used for degassing in high-speed printing of water-based inks to avoid ink misting, mottling, and maintain image clarity.
Adhesives and Industrial Cleaning: Eliminates foam during adhesive stirring and application to prevent glue deficiency and strength reduction in bonding layers; reduces foam generation of cleaning agents in industrial cleaning to avoid overflow from tanks.
Water Treatment and Papermaking: Suppresses foam formation in aeration, circulating water, and other processes to reduce overflow risks; controls foam during pulping and papermaking to prevent paper defects and air spots, improving paper formation and smoothness.
Textile Dyeing and Finishing and Metalworking: Provides long-lasting foam suppression under high temperature and high shear conditions to avoid dye spots, streaks, and ensure uniform dyeing of fabrics; inhibits foam accumulation in cutting, grinding, and other circulating systems to enhance cooling and lubrication effects.
