General Product Information Tech Sheet

Benefits at a Glance
Low foaming after application ensures easy identification of any remaining frozen deposits.

Excellent wetting properties avoid premature re-icing of already treated surfaces.

Improved inhibitor package allows the preparation
of fluid dilutions with water qualities of different hardness.

Fully biodegradable additive package, low surfactant content and triazole-free formulation gives superior environmental profile.

Benefits in Detail


Foam characteristics: Safewing MP I 1938 ECO was developed to include a minimum amount of surfactants which results in improved environmental properties and very low foaming characteristics.


Certification: Safewing MP I 1938 ECO is
certified according to the global standards
outlined by SAE AMS 1424.

Handling: Type I-fluids are usually applied in dilutions with water. Safewing MP I 1938 ECO includes a specific inhibitor package which allows the use of hard water while minimizing the
formation of any precipitates within the fluid.
