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

Description
STHAMEX AFFF 3% F-15 #4341 is a synthetic, aqueous film forming fire extinguishing foam concentrate, based on surface active agents.
Special surfactants, fluorinated components and freeze protection characterise the composition of this outstanding product.

Approval
♦ DIN EN 1568 Certificate No.: KB-290/14, Part 3 (Heptane): IB/IB, Part 1: Medium ex.—
♦ ICAO Airport Services Manual, Low expansion foam — Level B
♦ IMO MSC.1/Circ. 1312 non-polar (Heptane)

Properties
STHAMEX AFFF 3% F-15 #4341 forms foam very readily and is used for both low and medium expansion foam applications.
The film forming and re-ignition preventing ingredients of STHAMEX®-AFFF 3% F-15 #4341 provide for extremely fast and effective extinction especial-ly when used on class B fires.
The aqueous film formed out of the draining foam solution spreads extremely fast and enhances the flowing properties and burn-back resistance of the foam.
The extinction time is reduced considerably and the fire source cooled.
The aqueous film even extinguishes areas scarcely covered with foam and prevents re-igniting of areas, where the foam layer is ruptured.

The foam is stable and in combination with the aqueous film, it forms a lasting, gastight layer on flammable areas. Due to its high foam density a long throwing range can be achieved.
The foam is oleophobic, i.e. it does not pick up fuel and is therefore particularly suitable for “sub-surface” foam application.
On hydrocarbon products STHAMEX® AFFF 3% F-15 #4341 can be applied as non-aspirated, aqueous solution by means of e.g. water monitors, water sprinklers, deluge systems etc.
STHAMEX® AFFF 3% F-15 #4341 is not suitable for use on polar solvents, e.g. alcohols.
STHAMEX® AFFF 3% F-15 #4341 does not contain silicones.

Application:

  • Used at 3% concentration and applied with all standard low and medium expansion foam equipment and fixed foam installations especially for class B fires.
  • Can be applied using water monitors, water sprinklers or deluge systems.
  • Seawater, brackish water and treated industrial water do not affect the out-standing fire performance.
  • Used in petrochemical industries, on airports and in on-and offshore areas.
