Type I

DF Plus - De-icing Fluid

Type I fluids are primarily used for de-icing 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-icing then anti-icing process where a Type II or Type IV fluid is subsequently applied to provide the required holdover protection.

Kilfrost DF Plus

DE-ICING FLUID - exceeds all requirements of AMS 1424/ISO 11075

One of the most robust Type I Aircraft De-icing fluids on the market

Available in bulk, 1000L IBC, 215L drum and 20L can.

Kilfrost DF Plus is a low foaming propylene glycol-based Type I de-icing fluid that conforms to all of the technical requirements specified by the Society of Automotive Engineers Aerospace Material Specification SAE AMS 1424/1 for Type I and ISO11075 for Aircraft De-icing/Anti-icing Fluids. Kilfrost DF Plus does not contain any alkali organic salts e.g. formates/acetates.

Lowest Operational Use Temperature for a high take-off speed jet aircraft -32°C for a 69% dilution.
DF Plus has a shelf life of 3 years in original sealed containers. Stability tests under both thermal and cold storage conditions showed no significant change in pH, RI, viscosity or appearance. Thermal storage stability tests are carried out using neat fluid at 80°C for 30 days. The fluid remained homogenous at all times, WSET testing confirms aged fluids exceed the minimum requirements for anti-icing performance.
DF Plus diluted 1:1 in standard hard water does not show any significant changes in pH or appearance with no evidence of insoluble deposit seen. Hard water stability tests are carried out on fluid diluted 50% at 95°C for 30 days.
