Ground and Heli-torches require gelled fuel. PHOS-CHEK FLASH 21 is a two-part liquid fuel gelling agent that reliably provides high quality gel, fast. Fuel thickened with PHOS-CHEK FLASH 21 achieves ideal viscosity with no settling. FLASH 21 can be mixed with various fuels including straight gasoline, diesel, Jet A or Jet B if available. Using Jet A alone will produce a good gel but because of the low flash point of this type of fuel, you may need to add 20-30% straight gas to produce a better ignition point.
PHOS-CHEK FLASH 21 was developed to allow mixing with fuel regardless of temperature, ensuring a consistent gelled fuel mixture. Fuel treated with FLASH 21 will not lose viscosity, allowing use during an entire burning operation.
