The deicing composition described consists essentially of a) from 87 to 99.45 by weight of an alkali metal acetate or an alkali metal formate or a mixture thereof, b) from 0.5 to 10o by weight of an alkali metal silicate, and c) from 0.05 to 3o by weight of an alkali metal phosphate. It can be employed in solid form (powder, granules and the like) or in the form of an aqueous solution. It ensures a short thaw time and corrosion protection, especially with regard to magnesium.
L'invention concerne un dégivrant comprenant principalement: a) entre 87 et 99,45 % en poids d'un acétate de métal alcalin ou d'un formiate de métal alcalin ou un mélange des deux; b) entre 0,5 et 10 % en poids d'un silicate de métal alcalin et c) entre 0,05 et 3 % en poids d'un phosphate de métal alcalin. Il peut s'utiliser sous forme solide (poudre, granulat et similaire) ou sous forme de solution aqueuse. Cet agent garantit un temps de dégivrage réduit et assure une protection contre la corrosion notamment en considération du magnésium.
