Typical Applications
TEGO® Antifoam 691 is particularly suitable as pre-defoamer for a wide range of emulsifiable lubricants such as metalworking fluids (MWF) or fire-resistant hydraulic fluids (HFA).
It can be applied for soluble oils and semi synthetic fluids based on mineral oils or ester oils as well as for lubricants that are based on blends of those oils.
Depending on the composition of the fluid, TEGO® Antifoam 691 may also be suitable for water-soluble (full synthetic) fluids.

Benefits at a glance
TEGO® Antifoam 691
- Is a highly efficient defoamer concentrate even at low dosage levels
- Provides excellent foam knock down and hold down properties
- Offers a deaerating effect in water-mixed fluids
- Shows an outstanding long-lasting defoaming persistence
- Provides excellent filterability properties, which minimizes the amount of additional tank side defoamer
- Allows the formulation of emulsifiable lubricant concentrates with good storage stability
- Does not deteriorate the shelf-life of ready to use emulsions
- Is a homogeneous defoamer concentrate that shows no deposits even after one year of storageis free of silicone oil and thus has no adverse effects on finishing processes (e.g. painting, electroplating) of treated parts
