Polyether defoamer GP-330 is specially designed for water-based systems and is widely used in eight major industries: coatings, adhesives, inks, water treatment, textile printing and dyeing, papermaking, metalworking fluids, and industrial cleaning.

Main Application Industries and Processes

IndustrySpecific Process StageEffect
Water-based coatingsDispersion, mixing, coatingRapid defoaming, reducing craters and pinholes, improving surface quality
AdhesivesStirring, applicationEliminate bubbles, prevent adhesive layer from lacking glue and strength reduction
InksHigh-speed printingRapid deaeration, avoid ink misting and mottling, maintain image and text clarity
Water treatmentAeration, circulating water systemsSuppress foam generation, reduce overflow risk, improve system efficiency
Textile printing and dyeingHigh temperature and high shear conditionsLong-lasting foam suppression, avoid dyeing defects such as color spots and blotches, ensure level dyeing
PapermakingPulping, paper formingControl foam, prevent paper defects and air spots, improve paper sheet formation
Metalworking fluidsCutting, grinding circulation systemsSuppress foam accumulation, enhance cooling and lubrication effect and machining accuracy
Industrial cleaningCleaning agent applicationReduce foaming tendency, avoid foam overflow from the tank, ensure cleaning power

Core Performance

GP-330 (polyoxypropylene glycerol ether, CAS: 68439-50-9) is a nonionic surfactant with rapid defoaming and long-lasting foam suppression, high temperature resistance, strong chemical stability, and compatibility with various water-based resins and additives, and is not prone to causing coating defects such as craters and fisheyes.

Precautions

  • This product has strong physiological inertness and no significant hazard classification. It is recommended to wear protective gloves and goggles during operation.
  • Avoid direct discharge into water environment without treatment.
  • Store sealed in a cool, dry, and well-ventilated place, recommended temperature 5°C–35°C, avoid freezing and high temperature storage.
