Whats the difference between a deicers theoretical temperature limit and its practical temperature limit?
A theoretical temperature limit (eutectic temperature) is the lowest possible temperature at which a deicer at its ideal concentration is capable of working. Deicers become increasingly diluted as they melt their way through ice or snow. They do not remain at their ideal concentration for long. Practical temperature limits, on the other hand, are a more realistic measure of effectiveness because they refer to a deicer’s ability to melt through ice and snow under actual conditions in a reasonable amount of time.
