Glossary
Hygroscopic

A property of some materials to absorb or attract moisture from the air. #ChemicalandMaterialTerms


Glossary
Liquid

General term used to describe any deicer chemical in a liquid state. It can be used to pre-treat solid deicers, anti-ice, deice, or pre-wet solid deicers or reapplications. #ChemicalandMaterialTerms


Glossary
Exothermic

Noting or pertaining to a chemical change that is accompanied by liberation of heat. Synonym: Heat of the Brine. #ChemicalandMaterialTerms


Glossary
Eutectic Temperature/Eutectic Point

The lowest possible freezing point in a solution.


Glossary
Endothermic

Noting or pertaining to a chemical change that is accompanied by an absorption of heat. #ChemicalandMaterialTerms


Glossary
Effective Temperature

The lowest temperature at which it is cost effective or practical to use a deicer. (i.e., salt works down to -6° but under 15° becomes less effective, etc.). #ChemicalandMaterialTerms


Glossary
Deicer

A material to melt snow and ice. Commonly used deicers include sodium chloride, magnesium chloride, calcium chloride, and potassium chloride in either solid or solution (liquid) form. A deicer can be used in the anti-icing or deicing mode of operations. Synonym: Ice Melt.


Glossary
Cation Exchange

The displacement of calcium and magnesium ions in the soil by sodium ions, causing a decrease in soil permeability, aeration, and fertility. This exchange can have a negative impact on vegetation.


Glossary
Cake (verb)

Forming of a crust or lump(s)/clumping in a solid deicer material. (e.g., ‘The salt was caking in the spreader.’). (Source: https://en.wiktionary.org/wiki/cake ). #ChemicalandMaterialTerms


Glossary
Bounce and Scatter

The movement of a deicing material after it strikes a surface and scatters across or off of that surface. Variables that impact the propensity of deicers to scatter across pavement include velocity, surface type, material type, density and hardness. #ChemicalandMaterialTerms
