#antifreeze

• Antifreeze — A liquid chemical substance (usually based on ethylene glycol or propylene glycol) which, when added to water in the cooling systems of internal combustion engines or industrial installations, considerably lowers its freezing point and prevents structural damage to pipes due to ice expansion; antifreeze. As an adjective, it describes the property of a compound to prevent the solidification of fluids at low temperatures.
• Antifreeze — A special liquid (usually composed of ethylene glycol or propylene glycol) added to the water in cooling systems of internal combustion engines or heating installations, aiming to lower the freezing point of the mixture and prevent pipe damage; a concentrated coolant.
• Anti-icing fluid — Preventing or impeding the formation of ice; a liquid chemical substance (usually glycol or alcohol-based) sprayed on mechanical elements or added to fuel to lower the freezing point. As a noun, it designates the protective fluid utilized in preventative airport winter treatments.
• Antifreeze — Preventing, impeding, or combating the freezing of liquids or the formation of ice on various surfaces; a chemical substance, additive (such as antifreeze), or technical system utilized to lower the freezing point of water or to protect installations during winter. In a structural sense, it describes protective heating circuits or compounds that maintain solution fluidity at sub-zero temperatures.
