Airedale Chemical Antifreeze is an MEG based chemical additive which lowers the freezing point of a water-based liquid.
An antifreeze mixture is used to achieve freezing-point depression for cold environments and also achieves boiling-point elevation to allow higher coolant temperature. Freezing and boiling points are colligative properties of a solution, which depend on the concentration of the dissolved substance. Anti-freeze contains corrosion inhibitors. Airedale Chemical Antifreeze is a blue liquid (although other colour variants are available on request) with an MEG based odour.
