Description
Any of several products that contain a mixture of salts or other water soluble compounds used to melt ice from roads, sidewalks, and airplane wings. Solutions lower the freezing point of water by disrupting the formation of the crystalline structure of water. Examples are:
- Ammonium sulfate: to -7C, damages concrete
- Calcium chloride: to -29C, melts fast, hygroscopic, may re-ice
- calcium magnesium acetate (CMA): to -9C, safest for concrete/plants
- Magnesium chloride: to -15C, melts fast, hygroscopic
- Potassium acetate: to -9C, biodegradable, corrosive
- Potassium chloride: to -7C, damages concrete, kills plants
- sodium chloride: to -9C, keeps sidewalks dry, corrosive, kills plants
- urea: to -7C, concentrated form is corrosive and kills plants
- others: sugar, alcohols, glycol propylene glycol.
