Fomtec MB -20 is a multipurpose foam concentrate consisting of a blend of hydrocarbon surfactants, solvents and stabilisers.
All Fomtec multipurpose foam concentrates are totally free from fluorinated surfactants and polymers (PFAS).
The fire suppression mechanism of Fomtec MB -20 is utilising the foam blankets ability to block oxygen supply to the fuel and the high water content cools the fuel surface reducing the evaporation of flammable vapours.
Additionally, the foam blanket prevents reignition of an extinguished fuel surface.

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.
