WebbAircraft deicing/anti-icing fluids consist of four types. They are Type I, II, III, and IV. Deicing fluids are typically ethylene glycol, diethylene glycol or propylene glycol based fluids containing water, corrosion inhibitors, wetting agents and dye. Anti-icing fluids are similar in composition except that they also contain polymeric thickeners.
