(Commonly known as TKS™ Fluid — Kilfrost put the ‘K’ in TKS™)

Deicing Photo EcolinkDescription

DTD 406B aircraft in-flight ice protection fluid protects YOU and YOUR plane 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. Designed for use according to (POH) in TKS™  ice protection systems or “weeping wings”, the TKS 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 propwash area and behind the weeping panels.  It is also recommended for removing hoar frost, light snow/ice and frozen deposits from parked aircrafts.   Available in small (2.5 or 5-gal) and big (55 and 275 gal packaging) and ships same day, year round!order-now
