STHAMEX-AFFF 3% F-15 (#4341)
Mfg.: Dr.Sthamer – Hamburg

STHAMEX®-AFFF 3% F-15 (#4341)
STHAMEX®-AFFF 3% F-15 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 applied with all standard low, medium, and high expansion foam equipment and fixed foam installations especially for 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-15 (#4341) is not suitable for use on polar solvents, such as alcohols.
