DTD 406B Deicing Fluid for “weeping wings” on Cirrus aircrafts
(Commonly known as TKS™ Fluid -- Kilfrost put the 'K' in TKS™)



DTD 406B aircraft in-flight ice protection fluid protects YOU and YOUR Cirrus SR20, SR22, (G2, G3, G5, GTS) or Vision SF50 from in-flight freezing by distributing ice protection fluids through porous metal structures that form the leading edge of the wings and rear horizontal and vertical stabilizers. With 8-gallon holding capacity (4 per side) you can enjoy 2.5 hours of endurance.

Designed for use according to (POH) in ice protection systems or “weeping wings”, the deicing fluid meets DTD-406B standards and is made from an ethylene glycol based formula that effectively removes ice from engine inlet, cowl, flight controls, antennas, wing, tail, propeller, rudder, windshield and everything in the prop wash area and behind the weeping panels.  It is also recommended for removing hoar frost, light snow/ice and frozen deposits from parked aircraft.   Available in small (2.5 or 5-gal) and big (55, 275 and 330 gallon packaging) and ships same day, year round!



  • Meets AL-5 DTD 406B, NATO S-745
  • Excellent in-flight ice protection capability with freezing point below –76°F (-60°C)
  • Works for de-icing and anti-icing (curative and preventive for icing)
  • Easy to use: designed for use in cold concentrate form (undiluted as supplied)
  • Fluid runback provides total airframe ice protection
  • Controlled viscosity for dispensing at varied temperatures
  • Fully-biodegradable
