Industrial Silicon Defoamer Antifoamer Agent for Water Based Metalworking Fluids

Defoamer 689 concentrate is a high solid content, water dispersible organic silicon defoamer. It is stirred appropriately it can then be dispersed in water. It is specially developed for metalworking fluid 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 scope: Suitable for metal processing liquid systems

Performance characteristics:

*Rapid defoaming performance, maintaining excellent defoaming performance even after high temperatures.
