摘要
The invention relates to a defrosting agent comprising substantially: (a) 87 to 99.45 wt % of an alkali metal acetate or an alkali metal formate or a mixture thereof; (b) 0.5 to 10 wt % of an alkali metal silicate; and (c) 0.05 to 3 wt % of an alkali metal phosphate. Said agent can be used in the form of a solid (powder, granules and the like) or in the form an aqueous solution, and provides a short thawing period and protection against corrosion, in particular with respect to magnesium.
