Kilfrost RDF (Rapid De-icing Fluid) is a cold de-icing fluid, often used on GA aircraft. It doesn't meet SAE AMS 1424 (Type I fluid) or SAE AMS 1428 (Type II, III and IV fluid), so wouldn't be approved for use on most commercial aircraft.
Technically it would only be considered as being a de-icing fluid, as it offers no anti-icing protection.
