Potassium Acetate – Liquid Runway Deicer (PDF)

SAFE RUNWAYS AND A CLEAN ENVIRONMENT

SPEC: Potassium Acetate Liquid Runway Deicer

BENEFITS

  • Safe for runways: meets FAA approved specifications
  • Safe for the environment: non-persistent, biodegradable, low BOD
  • Fast: runways are available sooner
  • Staying power: works longer, requiring fewer applications
  • Easy to apply: applied with existing equipment

PERFORMANCE

  • Excellent anti-icing characteristics
  • Active at low temperatures (-20°F and below)
  • Less slippery than glycol-based products

APPLICATION

  • Deicing:
    • 1 gallon /1000 ft2 (50 g/m2) near 32°F (0°C) on thin ice
    • 3 gallons/1000 ft2 (150 g/m2)below 10°F (-12°C) on 1 inch ice
  • Anti-icing: 0.5 gallons/1000 ft2 (25 g/m2)
  • Reapply when new accumulation shows first tendency to bond
  • Plow often to reduce fluid dilution
  • Prewetting – apply at spreader outlet at a rate of 1.25 gallons per 100 Ibs. (130 g/kg) of solid deicer

ENVIRONMENT

  • Low BOD
  • Biodegrades at low temperatures
  • Does not contain urea
  • Low toxicity to fish, mammals, and vegetation

HANDLING

  • Polyethylene, carbon, low alloy, or stainless steel containers
  • Containers must be clean and free of rust, surface deposits, and residues
  • Do not use galvanized materials
