Polar guard advance polar guard advance is a propylene glycol based type iv aircraft deicing anti icing fluid that meets the current revision of sae ams 1428 1 with low viscosity for easier handling and application and the lowest operational use temperature lout in the industry.
Type 4 deicing fluid.
Similar to type ii fluids type iv fluids can be used in a variety of ways.
Unheated and undiluted or diluted for anti icing.
Designed to meet sae type i and ams 1424 specifications for de icing aircraft type 1 de icing fluid is made from propylene glycol.
This fluid is not to be used when temperatures are under 22 f.
Characterization and compliance with applicable laws are the responsibility solely of the generator.
For additional fluid requirements see reference section paragraph 4 1.
Water freezes at 0 c.
Ams 1424 type 1 deicing fluid page 2 of 9 p501.
Type ii and iv fluids may be applied heated or cold and diluted or full strength.
Type i fluids have the shortest hot.
For anti icing it is primarily the heat imparted to the airframe that accomplishes the task.
Treatment storage transportation and disposal must be in accordance with federal state provincial and local regulations.
Deicing fluids work best when they are diluted with water.
Colour for type ii fluids and green is the colour for type iv fluids.
The colour for type iii fluid has not yet been determined.
Type iv fluids offer maximum anti icing holdover protection but can also be used for de icing purposes.
Polar guard advance is supplied as a ready to use formulation.
The differences between type i and type iv de icing fluid.
Pearson airport cyyz faa link for information on de icing and anti icing fluids.
For de icing it is the heat and hydraulic force that accomplish the task.
For example undiluted dow ucar deicing fluid type i ethylene glycol has a freezing point of 28 c.
In general deicing anti icing fluid may be uncolored if so requested.
When a type i fluid fails it fails suddenly.
However a mixture of 70 percent deicing fluid and 30 percent water freezes below 55 c.
This fluid has a low viscosity and flows off of aircraft easily.
