Type 1- De-icing Fluid is a propylene glycol based de-icing product intended for use during ground de-icing of an aircraft. Sprayed onto the airplane fuselage, wings and tail to help remove the buildup of frozen containments (ice, snow and frost) prior to flight. This helps with aerodynamics to keep the plane flying safely and efficiently.

 

Type 4- Type IV Anti-icing fluid is specifically thickened so as to remain on the wings, tail and other aircraft externals, to prevent ice from forming. Type IV products are not used for ice removal, but rather for icing prevention.
