Fomtec MB -20

Fomtec MB -20 is intended for use on class B hydrocarbon fuels such as oil, diesel, gasoline and aviation fuels. Fomtec MB -20 can be used with all kinds on low, medium and high expansion devices. It is intended to be used at 3% proportioning. Fomtec MB -20 is also effective against class A fires such as wood, paper, textiles etc. at 0,3% to 1% proportioning. Typical applications are general firefighting of flammable liq-uids. Typical users are fire departments and general industry. Suitable for mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where application rates and technique can be adjusted to the specifics of each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.

Application

Fomtec MB -20 should be used at a 3% proportioning ratio (3 parts concentrate and 97 parts water) for hydrocarbon fuels. Fomtec MB -20 can be stored as premix when blended with fresh water.
For use on Class A type fires, induction ratio of 0,3% to 1% is recommended depending on application and discharge device.

Fire performance & Foaming
The fire performance has been measured and documented according to the “International Approvals” stated in this doc-ument. The use of the product should follow design guidelines appropriate to the type of system and application. The foam-ing properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 9:1, average 25% drainage time 03:30 minutes using UNI 86 test nozzle according to EN 1568-3.

Compatibility
Fomtec MB -20 is suitable for all water types. It is compatible with foam compatible dry chemical powders as well as other expanded foam types.
For mixing with other concentrates, contact Fomtec for advise and guidance. For material compatibility please refer to our Fomtec Technical Advices FTA 20 addressing the topic.

Environmental
Fomtec AFFF 3% is formulated using raw materials specially selected for their fire performance and their environmental profile. All raw materials are registered in European REACH database. Fomtec AFFF 3% is non-toxic, biodegradable and each individual component is fully tested and documented. Fomtec only use C6 Pure fluorosurfactants in our AFFF formulations. Our film forming (AFFF) products contains no PFOS or PFOA in accordance with US EPA Stewardship Programme 2010/15 and EU Directive 2017/1000. More details can be found in the Material Safety Datasheet (MSDS). The disposal of spills of concentrate or premix foam solution should be made in accordance with local regulations. For more detailed information please refer to our Fomtec Technical Advices FTA 40.

Storage/Shelf life
Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions. For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.

Inspection/Testing/Maintenance
The foam concentrate should be tested annually. The testing should be made by a suitable laboratory for analysis of foam concentrates and should measure: pH, specific gravity, expansion, drainage time. Storage containers should be inspected and reevaluated for the suitability of the storage location in regard to temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.
