Abstract

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 10% by weight of an alkali metal silicate, and c) from 0.05 to 3% 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.
