Type II de/anti-icing fluids are manufactured and qualified to AMS 1428 / ISO 11078 specifications. 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:
- Unheated and undiluted (or diluted) for anti-icing
- Heated and undiluted for de-icing / anti-icing as a one step process
- Diluted with water and heated for de-icing / anti-icing as a one step process
- Diluted with water and heated as the de-icing stage in a two-step process, when used with the unheated and undiluted fluid
Kilfrost offers two different Type II fluid options: ABC-3, which provides extended anti-icing holdover protection and ABC-K Plus, which offers extended hold especially in snow conditions.
