PHOS-CHEK® 3×6% AR-AFFF foam concentrate is a mixture of water, hydrocarbon surfactants, solvents, C6 fluorosurfactants and fluoropolymers. The product is a 3% x 6% concentrate that is intended to be proportioned at 3% for hydrocarbon fuel fires and at 6% for polar solvent fuel fires. PHOS-CHEK 3×6% AR-AFFF is designed for rapid control and knockdown by producing a thin aqueous film on hydrocarbon fuels or a polymer membrane on polar solvent fuels that minimize vapor release, a foam blanket that separates the fuel from the air, and continual draining of water from the foam blanket provides cooling at the fuel surface. 3×6% AR-AFFF’s may have given way to the more modern 3×3 AR-AFFF’s but many legacy systems still use 3×6%’s.
