TKS 406B (AL-5 to DTD 406B, NATO S-745)
Aircraft In-Flight De-/Anti-Icing Fluid
The TKS de-icing system protects aircraft from in-flight icing by pumping chemical through porous metal structures that form the leading edge of the wing. Propellers, windscreens and tail surfaces can be similarly protected if necessary.
TKS 406B contains a mixture of glycol and alcohol and offers good de-/anti-icing capability (freezing point below -60°C). Principally used for in-flight de-icing, TKS 406B can also be applied to remove frozen deposits of snow, ice and frost from stationery aircraft on the ground.
TKS 406B is designed for use in cold concentrate form (as supplied) and is available in 1 litre, 5 litre, 25 litre and 205 litre containers. For ordering information and technical assistance regarding this product, please contact a member of our Sales team (+44 (0)1434 321500).
