Defoamer 689 is a high solid content, water dispersible organic silicon defoamer. It can be

Dispersed in water after proper mixing. It is specially developed for metalworking fluids

Concentrate or mixture of various surfactants, and is used as defoamer to control foam.

the concentrated defoamer solution has good compatibility and high efficiency in

Defoaming performance, regardless of its application in non-ionic and anionic surfactant

Systems, and can also be used at high temperatures.

Active ingredient: Organosilicon

Application: Defoamer 689 has a wide range of applications and can be used in various

Production processes of metal processing liquid systems and textile industry (water-based

Systems).

Performance characteristics:

*Rapid defoaming performance, maintaining excellent defoaming performance even after

High temperatures.

*Excellent foam suppression durability.

*High efficiency high-temperature organic silicon foam suppressant and defoamer,

Especially suitable for production operations of non-ionic and anionic surfactant

Water-based systems.

*Suitable for strong alkaline working conditions, with good alkaline stability.

*Has excellent dispersibility in foaming liquid systems.
