high expansion firefighting foam

Dr Sthamer STHAMEX MARINE 3% F-20 #9372

Dr Sthamer STHAMEX MARINE 3% F-20 is a fluorine-free synthetic firefighting foam concentrate specially developed for marine fire protection applications. Manufactured by Dr. Sthamer in Germany, this product was designed as an alternative to fluoroprotein and AFFF foam concentrates in suitable maritime installations, including ship deck foam systems and offshore facilities.

The concentrate is proportioned at 3% and can be used to generate low- and high-expansion foam when paired with compatible equipment. Its low-temperature performance and low viscosity are intended to support operation in demanding marine environments. Always verify the current manufacturer datasheet and the specific system requirements before purchasing or using the product.

Key Features of Dr Sthamer STHAMEX MARINE 3% F-20

• Fluorine-free formulation: Manufactured without intentional addition of organofluorine compounds for performance improvement, according to the manufacturer's definition.
• 3% proportioning rate: Designed for the specified marine firefighting applications.
• Low- and high-expansion foam: Supports both foam types with suitable equipment.
• Marine application: Developed for shipboard, deck foam and offshore fire protection systems.
• Cold-temperature performance: Rated for use at temperatures down to -20°C, according to the manufacturer.
• Low-viscosity concentrate: Helps support use with compatible commercially available proportioning and dosing equipment.
• Suitable for seawater applications: Manufacturer documentation describes testing for specified marine applications using seawater.

How Does STHAMEX MARINE 3% F-20 Work?

Dr Sthamer STHAMEX MARINE 3% F-20 produces a foam blanket that covers suitable non-polar flammable liquid surfaces. The low-expansion foam forms a stable, vapour-tight layer that helps suppress the release and spread of flammable vapours. High-expansion foam can be generated for suitable applications using compatible foam-generation equipment.

Firefighting performance depends on the fuel, foam application method, proportioning rate, equipment design and site conditions. The product should only be used for hazards and applications confirmed in the manufacturer's documentation.

Recommended Mixing Concentration

The manufacturer's specified proportioning rate is 3% for the relevant low- and high-expansion foam applications.

Use suitable proportioning equipment to deliver the correct concentration. Confirm water supply requirements, foam-generator compatibility, operating pressure and the required application rate before integrating the concentrate into an existing firefighting system.

Applications of Dr Sthamer STHAMEX MARINE 3% F-20

This marine foam concentrate may be considered for suitable fire protection requirements in environments such as:

• Commercial ships and tankers
• Ship deck foam systems
• Offshore platforms and drilling installations
• Marine fuel handling areas
• Port and terminal facilities
• Other maritime locations with suitable non-polar liquid fire hazards

The manufacturer identifies marine use and specific fire-test performance in its documentation. Final selection must account for the vessel or installation design, hazard assessment, relevant standards and approval requirements.

Fluorine-Free Marine Firefighting Foam

Fluorine-free foam concentrates offer an alternative to traditional fluorinated firefighting foams for appropriate applications. The manufacturer describes STHAMEX MARINE 3% F-20 as a fluorine-free alternative developed for marine environments.

Fluorine-free status does not remove the need for proper storage, discharge management and environmental compliance. Follow local regulations and the manufacturer's instructions for handling foam concentrate and managing firefighting runoff.

Compatibility and Maintenance

Before using Dr Sthamer STHAMEX MARINE 3% F-20 in an existing foam system, verify compatibility with proportioners, pipes, tanks, seals, foam generators and discharge equipment. Replacing an existing foam concentrate may require specialist review, flushing or cleaning procedures.

Store the product according to the manufacturer's temperature and handling recommendations. Refer to the current safety data sheet for personal protective equipment, spill response and disposal guidance.
