Aircraft De-Icing Fluids
DAVIES “DE-ICING FLUID TYPE I” meets the latest SAE Type I and AMS 1424 specifications for aircraft de-icing. Propylene glycol is used in this product, to ease health and environmental concerns. This formulation is a de-icing fluid, designed for application directly on ice coating aircraft surfaces.
DAVIES “DE-ICING FLUID TYPE IV” meets the latest SAE Type IV and AMS 1428 specifications for aircraft ice retardation. This formulation is specifically thickened so as to remain on the wing and other aircraft externals, to prevent ice from forming. Type IV products are not used for ice removal, but rather for icing prevention. Propylene glycol is used in this product to ease health and environmental concerns.
Directions For Use
DE-ICING: Apply “DE-ICING FLUID TYPE I” as is, or for enhanced performance, diluted 50/50 and heated (160°- 180°F), with water. Do not use at temperatures below 22°F and always apply aft symmetrically (both left and right sides treated similarly), otherwise flight performance will be affected.
ANTI-ICING: To ice-free aircraft apply “DE-ICING FLUID TYPE IV”, as is to form a thin film on surfaces, to wings and aircraft exterior aft of wings. Aircraft must be sprayed symmetrically the same on both sides otherwise flight performance will be affected!! DO NOT USE BELOW -20°F!!!
DAVIES “TYPE 1” Aircraft Deicing Fluid must be used diluted and heated, in accordance with FAA approved deicing/anti icing program. This FAA approved program should reference SAE ARP 4737 & ISO 11076.
Please reference the following chart and graph which shows freeze point information for “TYPE 1” and water mixtures. When temperatures below –18°C, (0°F), are expected, use “TYPE 1” at 55/45 dilution with water. For temperatures below -26°C (-12°F), use at 60/40 dilution with water. Always select the dilution to maintain a temperature buffer of at least 10°C, (18°F) lower than the outside air temperature (DAT) or the aircraft’s skin temperature, whichever is lower.
