Deicing and Anti Icing Fluid
Hi
Out of the 4 types of deicing/anti icing fluids (Types 1,2,3 and 4) which can be used as decing fluids, and which as anti icing fluids?
I've looked at Wikipedia, however it is contradicting other information I have been given.
Thanks

de/anti-icing
All types can be used for deicing and most of them for antiicing purposes also. The thing is that as types increase from 1 to 4 so does the price...
Type I fluids are primarily used for deicing and do not offer any significant anti-icing holdover protection. 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 fluid provides the required extra protection.
Type II fluids can be used for deicing purposes but (unlike Type I fluids) also offer extended antiicing holdover protection and can be used in a variety of ways:
Unheated and undiluted (or diluted) for antiicing
Heated and undiluted for deicing / antiicing as a one step process
Diluted with water and heated for deicing / antiicing as a one step process
Diluted with water and heated as the deicing stage in a two step process, when used with the unheated and undiluted fluid.
Type III is not used very often. I cant remember why..
Type IV fluids offer maximum antiicing holdover protection, but can also be used for deicing purposes. Similar to Type II fluids, Type IV fluids can also be used in a variety of ways:
Unheated and undiluted (or diluted) for antiicing
Heated and undiluted for deicing / antiicing as a one step process
Diluted with water and heated for deicing / antiicing as a one step process
Diluted with water and heated as the deicing stage in a two step process, when used with the unheated and undiluted fluid as step two.
