Class A WD881 Foam, 5 gallons, Phos-Chek It bonds with just aWater, as it is converted into steam, has tremendous capacity to absorb and carry away heat. Unfortunately, water's strong surface tension causes it to bead up and roll off most fuels and away from heat too fast to be able to absorb its full heat capacity. Phos Chek's unique combination of surfactants significantly reduces water's surface tension. SPECS: Stretches out the water droplet into a bubble and holds it that way, increasing its heat absorbing
