Defoamer King FAG470 (also known as FAG-470, silicone defoamer, polyether-modified silicone defoamer, Defoamer FAG470) is a non-ionic defoamer produced by Haian Guoli Chemical Co., Ltd., with the chemical composition of polyether-modified polysiloxane. The product is supplied in an easy-to-use aqueous emulsion form, appearing milky white, and can be instantly dispersed in water, making it an ideal choice for controlling foam problems in industrial processes. Its unique molecular structure design enables it to exhibit rapid foam breaking and long-lasting foam suppression in various complex systems.
The core advantages of the product include: achieving efficient defoaming and long-term foam inhibition with extremely low dosage; stable chemical structure under harsh conditions such as high temperature and strong alkalinity, not prone to demulsification or failure; non-ionic formulation makes it easily dispersible in water and has good compatibility with other additives in the system, unlikely to cause adverse reactions or turbidity.

With its excellent comprehensive performance, Defoamer King FAG470 is mainly used in the following seven industrial fields (data source: Guoli Chemical Product Database):
Before use, gently stir the product to ensure uniformity. It can be added directly or diluted with several times of water before adding to the foaming system. It is recommended to add continuously via a metering pump to the foam generation area for optimal defoaming and foam inhibition effects. The specific dosage should be determined through small-scale tests based on actual working conditions and foam levels. Usually, a very low dosage can achieve the desired effect. The product should be stored at a temperature between 5°C and 40°C, avoiding freezing or prolonged high temperatures to maintain stability.
This product is not classified as a hazardous chemical according to GHS standards; it is non-flammable, non-oxidizing, and has no known acute toxicity or irritation. However, it is still recommended to wear personal protective equipment such as protective gloves and safety glasses during operation to avoid prolonged skin contact and eye contact. If accidentally splashed into the eyes, rinse immediately with plenty of running water for at least 15 minutes and seek medical attention promptly. After opening, use as soon as possible. Keep the container sealed during storage, away from strong oxidizers, strong acids, strong bases, and other incompatible substances.
