Product description

AIL Defrost EG 4 type IV liquid is produced in the concentrated (100%) form, which is an aqueous solution of monoethylene glycol with addition of a special thickener, anticorrosive additives, surfactants and dye. The thickener gives properties, manifested in reduction of the initially high AIL viscosity registered as the shear stress increases (increasing velocity of the air flow over the surface covered by AIL), it is colored in green.

The liquid meets the requirements of SAE AMS 1428/1, approved by the International Certification Center AMIL (Canada), included in Holdover Time (HOT) Transport Canada, Holdover Time (HOT) FAA, based on its performance characteristics.
