TEGOSTAB® B 8737 LF 2 is our strongest TDI foam stabilizing silicone surfactant for the manufacturing of polyurethane foam. For most standard formulations too potent as a sole surfactant, combinations with a cell regulator are recommended.
Typical Applications
TEGOSTAB® B 8737 LF 2 is primarily used in a combination with a cell regulator (e. g. TEGOSTAB® B 8724 LF 2) for predominantly TDI80/20 based foams.
Benefits at a glance
- Very high potency
