Type 2 Deicing Fluid

Type ii fluids can be used for de icing purposes but unlike type i fluids also offer extended anti icing holdover protection and can be used in a variety of ways.

Type 2 deicing fluid.

Aircraft de icing clariant has developed high performing deicing fluids to keep aircraft surfaces free from ice and snow. Discover our portfolio of de icers. Recycling clariant supports our customers efforts to reduce the environmental impact of their airport operations and lower costs. Water freezes at 0 c.

Unheated and undiluted or diluted for anti icing. For example undiluted dow ucar deicing fluid type i ethylene glycol has a freezing point of 28 c. Because of this type i fluids are commonly used as part of a two step de anti icing procedure when the final application of a type ii or type iv. 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. For de icing it is the heat and hydraulic force that accomplish the task. Type ii and iv fluids may be applied heated or cold and diluted or full strength. For anti icing it is primarily the heat imparted to the airframe that accomplishes the task.

This fluid is not to be used when temperatures are under 22 f. The differences between type i and type iv de icing fluid. Deicing fluids work best when they are diluted with water. When a type i fluid fails it fails suddenly.

Designed to meet sae type i and ams 1424 specifications for de icing aircraft type 1 de icing fluid is made from propylene glycol. Type ii de anti icing fluids are manufactured and qualified to ams 1428 iso 11078 specifications.
