Abstract

L'invention concerne une composition pour dégivreur liquide peu corrosif exempt de chlorure, qui comprend: de 6,3 % à 7,7 % en poids de propylène glycol, de 1,8 % à 2,2 % en poids de sulfonate de potassium, de 1,8 % à 2,2 % en poids de succinate disodique, de 18 % à 22 % en poids d'éthanol, de 8,1 % à 9,9 % en poids d'acide acétique et de 56 % à 64 % en poids d'eau. Cette composition n'est ni corrosive pour les métaux et le béton, ni toxique pour les poissons et ne pollue pas le sol, même en cas d'infiltration du dégivreur dans les rivières et dans le sol; elle permet de prévenir efficacement un phénomène de recongélation consécutif à l'élimination de la glace et de la neige, et est plus écologique qu'un dégivreur classique.
