Polyether Defoamer GP-330 is a nonionic glycerol polyoxypropylene ether specifically designed for water-based systems, featuring outstanding characteristics such as rapid foam breaking, long-lasting foam inhibition, high temperature resistance, and strong chemical stability.

Core Characteristics

CharacteristicDescription
Rapid Foam BreakingBreaks generated foam within a very short time, quickly restoring normal system operation
Long-lasting Foam InhibitionContinuously exerts foam inhibition, effectively preventing foam regeneration
Excellent Temperature ResistanceMaintains stable defoaming activity under high temperature conditions, not prone to decomposition or failure
Strong Chemical StabilityResistant to acidic, alkaline environments and hard water conditions, remains reliable in complex systems
Broad ApplicabilityCompatible with various water-based resins, additives, and formulation systems, less likely to cause shrinkage cavities, fish eyes, and other coating defects
Easy to UseLiquid form facilitates metering and addition, disperses evenly, not prone to stratification or sedimentation

Physical and Chemical Form

The product appears as a colorless to light yellow transparent viscous liquid, with good water dispersibility and system compatibility. Its CAS number is 68439-50-9, and its chemical name is Glycerol Polypropylene Ether (also known as C12-14 Alcohol Polyoxyethylene Polyoxypropylene Ether, Fatty Alcohol Polyether).

Applicable Fields

Widely used in water-based coatings and adhesives, water-based inks, industrial water treatment, textile printing and dyeing, papermaking, metalworking fluids, and industrial cleaning, among other water-based systems.

Safety Tips

This product is a non-hazardous substance with strong physiological inertness. It may cause mild mechanical irritation to skin and eyes. It is recommended to wear protective gloves and goggles during operation. Avoid direct discharge into water environments without treatment.
