      Anti-Icing Fuel Additives

HI-Flash™ anti-icing aviation fuel additive. MIL-I-85470(A) APPROVED AND BY THE ASTM UNDER STANDARD D4171 (for use in civilian jet fuels as a fuel system icing inhibiter).

For safe flying, all aircraft without fuel heaters should use an anti-icing fuel additive. Safer and easier to handle than conventional anti-icing fuel additives. PPG Industries developed Prist® Hi-Flash™ anti-icing aviation fuel additive to meet the new demands of the aviation industry. Next-generation Hi-Flash is less toxic, less volatile and much easier to use than conventional additives. It’s also from PPG, an aviation leader for more than six decades.

Why you should use a fuel additive. The formation of ice crystals in fuel tanks can block the aircraft’s fuel line or filter, causing engine failure. Prist Hi-Flash anti-icing aviation fuel additive controls icing in aircraft fuel by depressing the freezing point of water. All turbine aircraft fuels contain some dissolved water. It cannot be extracted because it does not exist as particulate water. When an aircraft rises to flight altitude, the fuel cools and its capacity to retain dissolved water is reduced. Some of the dissolved water separates out as discrete water that can form into ice crystals or remain as a super-cooled liquid. When super-cooled water strikes a tubing bend or a filter, it can freeze quickly and block a fuel line or filter.
If suspended ice crystals are present, they can also block a filter.

Controlling Fuel System Icing. Prist Hi-Flash additive has limited solubility in jet fuel, but is completely soluble in water. When dissolved water separates from the fuel, some amount of Prist Hi-Flash additive quickly leaves the fuel and preferentially dissolve in the water. This depresses the water’s freezing point. As the fuel gets colder, and more water particles appear, more Prist Hi-Flash additive leaves the fuel and enters the water, and your aircraft’s fuel lines stay clear.

Fully Authorized. As part of its ASTM approval process, the formulation of Prist Hi-Flash was reviewed and approved by turbine engine and turbine aircraft airframe manufacturers worldwide. Prist Hi-Flash is recommended for every refueling at a dosage rate of .1% minimum to .15% maximum by volume. For your convenience, Prist Hi-Flash comes in four package sizes:

  • 5-Gallon Pail—Holds enough Prist additive to treat 5,000 gallons of fuel.
  • 55-Gallon Drum—For the most economical bulk treatment of fuel.
  • 20 oz. Hi-Flo aerosol cans.
  • 8 oz. Lo-Flo aerosol cans.

Handling and Storage. Prist Hi-Flash aviation fuel additive should be handled as a combustible liquid and stored away from direct sunlight and other sources of heat. The flammable limits of its vapor range from 1.2% to 22% in the air. Prist Hi-Flash additive should be protected from contact with oxidizing agents, including long- term contact with the air, as it can combine with oxygen to form explosive peroxides, and since exposure to the atmosphere may cause it to absorb moisture. Carbon dioxide, alcohol-type foam, or dry chemicals should be used for extinguishing a Prist Hi-Flash fuel additive fire, since water may cause frothing.

Health Hazards. Acute—Diethylene glycol monomethyl ether (DEGMME), the primary ingredient of Prist Hi-Flash aviation fuel additive, is an eye and mucous membrane irritant, a nephrotoxin and central nervous system depressant. DEGMME can be absorbed through skin in toxic amounts when contact is extensive and prolonged; it is toxic by skin absorption. And it may cause pain and transient injury to eyes. DEGMME may cause irritation to the mucous membranes. Due to the low volatility of this material, it is believed to present no unusual hazards from inhalation when handled at room temperature. The oral toxicity of DEGMME is low. Chronic—Fetal development abnormalities and effects on fertility have been reported to occur from prolonged ingestion by rats, mice and rabbits. For additional information, please consult the MSDS for this product.

Backed by PPG Industries. Prist Hi-Flash aviation fuel additive is produced under stringent quality control methods. The PPG technical staff is available for consulting on the handling, storage and use of the additive.

  Anti-Icing Fuel Additives
Prist® Hi-Flash™ Hi-Flo™ anti-icing aviation fuel additive. MIL-I-85470 (A) APPROVED AND BY THE ASTM UNDER STANDARD D4171 (for use in civilian jet fuels as a fuel system icing inhibitor). The 20-ounce can’s trigger dispensing system has been redesigned to offer safer and more convenient delivery when refueling. It starts with a trigger assembly designed to snap onto the can easier and stay attached, eliminating leaks at the valve connection. To avoid accidental dispensing, the new system incorporates a safety tab which must be removed before you can dispense Prist Hi-Flash Hi-Flo fuel additive. A new safety trigger gives the user control of the additives flow with instant on and off dispensing. And the dispensing tube now is pressure-fit, which means it can’t detach or blow off. This more accurate system means there is adequate pressure to fully evacuate the can; you will never get a short dispense. All of these features add up to a safer, more convenient and accurate system, with less waste, no drips and no spills. And all this with no price increase.

Directions for use

Prist Hi-Flash Hi-Flo anti-icing aviation fuel additive is recommended for every refueling at a dosage rate of .1% minimum to .15% maximum by volume. Use with fuel flow of 40–55 GPM.

  • Remove red overcap.
  • Carefully press trigger assembly (attached to tube with clip assembly) onto the valve on top of the can.
  • Remove and dispose of red safety tab on top of trigger assembly.
  • Place clip with tubing into fuel nozzle.
  • To start additive flow, squeeze trigger and continue holding during fueling. To stop flow, simply release the trigger.
  • Hold can upright and start flow after refueling begins and stop flow a moment before refueling ends.

Caution: Assure that Prist Hi-Flash Hi-Flo fuel additive is directed into and blends with flowing fuel from refueling nozzle. Do not allow concentrated additive to contact coated interior of fuel tank or coated surface of aircraft.

Why you should use a fuel additive. The formation of ice crystals in fuel tanks can block the aircraft’s fuel line or filter, causing engine failure. Prist Hi-Flash Hi-Flo anti-icing fuel additive controls icing in aircraft fuel by depressing the freezing point of water. All turbine aircraft fuels contain some dissolved water. It cannot be extracted because it does not exist as particulate water. When an aircraft rises to flight altitude, the fuel cools and loses its capacity to retain dissolved water, which separates out as discrete water that can form into ice crystals or remain as a super-cooled liquid. When super-cooled water encounters a tubing bend or a filter, it can freeze quickly, creating a fuel line block. If suspended ice crystals are present, they can also block a filter.

Fully Authorized. As part of its ASTM approval process, the formulation of Prist Hi-Flash Hi-Flo additive was reviewed and approved by turbine engine and turbine aircraft airframe manufacturers worldwide.

Handling. When handling, wear chemical safety glasses, rubber gloves and a long-sleeved shirt. Wear respiratory protection in any event where excessive exposure might result. Carbon dioxide, alcohol-type foam, or dry chemicals should be used for extinguishing a fire associated with Prist Hi-Flash Hi-Flo additive, since water may cause frothing.

Storage. Store in a cool, dry, well-ventilated place, away from direct sunlight and other sources of heat. Keep cans tightly capped to avoid excessive contact with air.

Precautions. Avoid breathing vapors. Inhalation over-exposure may irritate mucous membranes. Avoid contact with eyes, skin and clothing. Liquid or vapor can be absorbed through the skin and may cause severe illness. Contact may also cause local pain and irritation. Keep away from heat, sparks and flame. Use only with adequate ventilation. Ventilation must be adequate to limit employee exposure in the workplace.
