Mfg.: Dr.Sthamer – Hamburg
STHAMEX®-AFFF 3% F-10 (#4301)
STHAMEX AFFF 3% F-10 is a synthetic, aqueous film-forming fire-extinguishing foam concentrate based on surface-active agents. It is designed for use at a 3% concentration and is compatible with all standard low-expansion foam equipment and fixed foam installations, particularly for combating Class B fires.
Key Features:
– Oleophobic Properties: The foam is resistant to fuel contamination, making it particularly suitable for sub-surface foam applications.
– Application Versatility: On hydrocarbon-based products, it can be applied as a non-aspirated aqueous solution using equipment such as water monitors, water sprinklers, and deluge systems.
Applications:
– Petrochemical industries
– Airports
– Onshore and offshore facilities
Limitations:
– STHAMEX®-AFFF 3% F-10 is not suitable for use on polar solvents, such as alcohols.
