Defoamer King FAG470 is a non-ionic high-efficiency emulsion defoamer based on polyether-modified polysiloxane technology, featuring fast defoaming speed, long-lasting foam suppression, high temperature and strong alkali resistance, excellent dispersion, and safety and environmental friendliness as its core characteristics.

Detailed Description

Defoamer King FAG470 adopts a unique polyether-modified polysiloxane molecular structure design, exhibiting dual effects of rapid bubble collapse and long-lasting foam inhibition in various complex systems. An extremely low dosage can quickly eliminate existing foam and inhibit foam regeneration over a long period, effectively improving production efficiency and preventing material overflow loss. The product is provided in an easy-to-use aqueous emulsion form that disperses instantly in water, making it an ideal choice for foam control in industrial processes.

This product possesses excellent high temperature and strong alkali resistance stability. Under harsh working conditions such as high temperature and strong alkalinity, the chemical structure remains stable, resistant to demulsification or failure, and continuously maintains excellent defoaming performance. It is particularly suitable for high-temperature alkaline baths in textile printing and dyeing processes such as scouring, bleaching, and dyeing, as well as high-temperature and high-pressure scenarios in petrochemical industries. Meanwhile, its non-ionic formulation endows the product with superior dispersibility in water, allowing it to rapidly and evenly distribute in the foaming medium, ensuring performance without dead spots.

Defoamer King FAG470 has broad chemical compatibility. Its non-ionic nature ensures good compatibility with other additives in the system, making it less prone to adverse reactions or causing system turbidity, especially suitable for complex formulation processes. In terms of safety and environmental protection, the product is not a hazardous chemical, is non-flammable, has no acute toxicity, and is non-irritating to skin and eyes, ensuring safe and reliable use.

Application Suggestions

Defoamer King FAG470 is widely used in the following typical areas:

  • Water Treatment: Foam control in aeration tanks, sedimentation tanks, and thickeners of municipal sewage and industrial wastewater treatment systems.
  • Paint and Ink Manufacturing: Suppressing micro-bubbles and large bubbles in processes such as high-speed dispersion, grinding, and filling to prevent coating defects.
  • Textile Printing and Dyeing Processing: Defoaming tasks in high-temperature alkaline baths during desizing, scouring, bleaching, dyeing, and printing.
  • Industrial Cleaning: Foam control in high-pressure spraying, ultrasonic cleaning, and CIP online cleaning systems.
  • Metalworking Fluids: Maintaining lubricating and cooling performance in circulating cutting fluids and grinding fluids, preventing tank overflow.
  • Petrochemical Processes: Defoaming in oil-gas separation, amine solution desulfurization, ethylene glycol dehydration, and reactors, distillation towers.
  • Pulp and Paper: Foam control in pulping, paper machine wet end, and coating processes, improving paper formation quality.

Before use, gently stir the product to achieve uniformity. It can be added directly or after diluting with several times of water into the foaming system. It is recommended to add continuously via a metering pump to the foam generation area for optimal defoaming and foam suppression effects. The specific dosage should be determined through small-scale tests based on actual working conditions and foam level.

Precautions

  • Store at a temperature between 5°C and 40°C, avoid freezing or continuous high temperature to prevent product stability issues.
  • Wear protective gloves and safety goggles during operation to avoid contact with eyes, mucous membranes, and prolonged skin contact.
  • Use up the product as soon as possible after opening, keep the container sealed to prevent moisture absorption or external contamination.
  • Keep away from incompatible substances such as strong oxidizers, strong acids, and strong alkalis; store separately.
