This fluid is not to be used when temperatures are under 22 f.
Type 4 deicing fluid.
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.
Characterization and compliance with applicable laws are the responsibility solely of the generator.
The differences between type i and type iv de icing fluid.
Deicing fluids work best when they are diluted with water.
Type i fluids have the shortest hot.
Water freezes at 0 c.
For de icing it is the heat and hydraulic force that accomplish the task.
This fluid has a low viscosity and flows off of aircraft easily.
For anti icing it is primarily the heat imparted to the airframe that accomplishes the task.
Type ii and iv fluids may be applied heated or cold and diluted or full strength.
However a mixture of 70 percent deicing fluid and 30 percent water freezes below 55 c.
Type iv fluids offer maximum anti icing holdover protection but can also be used for de icing purposes.
In general deicing anti icing fluid may be uncolored if so requested.
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.
The colour for type iii fluid has not yet been determined.
Type iv de anti icing fluids are manufactured and qualified to ams 1428 iso 11078 specifications.
Treatment storage transportation and disposal must be in accordance with federal state provincial and local regulations.
1 1 1 fluid handling and storage.
For example undiluted dow ucar deicing fluid type i ethylene glycol has a freezing point of 28 c.
When a type i fluid fails it fails suddenly.
Regulations may vary in different locations.
For additional fluid requirements see reference section paragraph 4 1.
Polar guard advance is supplied as a ready to use formulation.
Pearson airport cyyz faa link for information on de icing and anti icing fluids.
Colour for type ii fluids and green is the colour for type iv fluids.
