Silicone defoaming agents are available in oil, solution, powder, and emulsion types. They all have a high defoaming effect when added in small amounts to all types of foaming liquids.


  • Defoaming effect
  • These agents cure to form thin film coatings via chemical reaction.

  • Safety
  • Silicone defoaming agents are highly safe, especially those for food applications, which meet the standards for food additives laid out in Japan's Food Sanitation Law.

  • Heat resistance and chemical resistance
  • Silicone defoaming agents have good resistance to heat and chemicals, so they are effective with all types of foams and can be used in conditions in which organic defoaming agents cannot.

  • Foam-inhibiting effect
  • Silicone defoaming agents have longer-lasting effects than other defoaming agents, and are also effective in preventing foaming from occurring.

  • Chemical stability
  • They are chemically inactive, so they are extremely stable and do not attack or react with other substances.
