FOAM BAN® 439
America · Asia/Oceania · EMEA
Product Details
FOAM BAN® 439 is an organo-modified siloxane-based antifoam that provides excellent foam control in non-aqueous lubricants, particularly synthetic base oils (Groups III+, IV, and V).
It is designed to be low viscosity so that it can be easily incorporated into an additive package or finished lubricant. FOAM BAN® 439 can also be evaluated as an alternate to fluorosilicone antifoams used in non-aqueous lubricants. FOAM BAN® 439 is especially developed for MOSH/MOAH-free applications.
Main applications:
- EV Driveline Fluids
- EV Thermal Fluids
- Transmission Fluids
- Engine Oils
- Gear Oils
- Hydraulic Oils
- Cutting Oils
