ABSTRACT:
The deicing composition described comprises essentially a) from 87 to 99.45% by weight of an alkali metal halide and/or an alkaline earth metal halide, 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 as an aqueous solution. It ensures a short thaw time and protects metals, especially steel, against corrosion.
