Given the complexity of field conditions, some aspects of liquid performance may seem to be a “black box,” and at times it can be difficult to know how to best use them based upon field experience alone. This challenge is increased by the fact that we use liquids in a variety of ways, from anti-icing to pre-wetting to direct liquid application (DLA) deicing, and liquids perform differently depending on the application. This presentation will show how we can apply the basic science of liquid deicers to complement our field-based knowledge to better select the right liquid and rate for different conditions and application types. Topics will include how liquids perform differently in anti-icing, pre-wetting, and DLA; the important liquid properties for these different types of application; how we can utilize freezing point curves as powerful tools to predict liquid performance; and how we can apply the basic science to guide the use and expectations of brine additives and blends.
