摘要:
The invention relates to an anti-freeze composition and preparation for making surfaces free of snow and ice, comprising in an amount of 20 to 90% by weight a waste concentrate of alcohol distilling industry, having a dry-substance content of 200 to 750 g/kg, in admixture with 10 to 80% by weight of water and optionally with additives.The composition is neither detrimental to environment nor does it exhibit any corrosive effect, and it can be used under optional weather conditions. It uniformly cools the surface to be melted and preserves the road surface.
