Ice Melting Materials - Buyer Choices
Ice melting materials are needed to guarantee the maximum possible safety for the people who must use roads, parking lots and sidewalks when snow/ice is present. This article lists the various ice melting materials from which a buyer can choose and explains why an ice melt blend may be the best choice.
It should be noted that an ice melting material is often referred to as an "ice melter" or just an "Ice melt". Also, these ice melting materials can be purchased in a mix (blend) or in their purest state. Many of the ice melt blends also include additives for the mix to improve the performance by reducing undesirable side effects. The list below includes the common buyer choices during the winter months to provide safer roads, parking lots and sidewalks.
• Inorganic salts - Salts can be inorganic or organic. Inorganic salts are compounds that contain chloride. Because of ready availability and lower cost, this category of ice melter is used more than any other category. Though high concentrations of inorganic salt can damage vegetation, Mother Nature's rain quickly dilutes these salts thereby minimizing damage to the environment. Four inorganic salts used to melt ice are:
1) Sodium chloride (NaCl, "rock salt" or "Halite")
2) Potassium chloride (KCl)
3) Magnesium chloride (MgCl2)
4) Calcium chloride (CaCl2)
• Organic salts - This category of ice melter includes acetate compounds. Because acetates are biodegradable (capable of decay), acetates are the safest for the environment. High cost limits the usage of acetates (some cost 30 times the cost of rock salt) as an ice melter. Three common acetates used to melt ice are:
1) Sodium acetate (NAAC)
2) Potassium acetate (KAC)
3) Calcium magnesium acetate (CMA)
• Non-salts - Because this category of ice melter will not corrode metal it is used primarily in airports. These products can have a very negative impact on the environment if not properly contained and disposed whenever used in high concentrations to melt ice. Caution should be used in selecting products that contain these materials. Three materials used to melt ice which are non-corrosive to metal are:
1) Urea
2) Glycol - Ethylene glycol is a liquid deicer
3) Fertilizers - in many milder climates retailers will market various fertilizers
• Non-ice melting materials - This category of material is often added to the ice melters above to improve traction and to lower material application cost. The major disadvantage is that they can cause significant inside tracking problems and outdoor clean up after the ice/snow has melted. Three commonly used materials for improved traction are:
1) Sand
2) Cinders (similar to what is found on a high school running track)
3) Calcianated Clay (also called "Turf Face Builder" which has a texture like cat litter)
In the last 10-20 years new processing methods at the manufacture have been developed which allow the granules of the materials to be liquid coated with other ice melting materials and/or additives. The materials on the outside of the granule provide faster results, better corrosion protection, safer handling, color to monitor application rates, etc. At the same time, the materials on the inside of the granule can be less costly, and/or safer for concrete, etc. depending on the specific manufacture's development intentions and testing.
For greater details on selecting a blend to melt ice, Google the article "Ice Melters - How Salt Granules Work". Though no manufacture shares the exact formulation of a blend, taking the time to learn more about ice melt blends in general will likely provide significant rewards for a buyer. These blends have the potential to significantly reduce application rates, speed up the melting process, lower the melting effective temperature (MET), reduce corrosion, increase shelf life without "caking", make a product more pet friendly, etc.
At the same time, there is a risk that a buyer may pay more while getting less because of a recent trend where these ice melt blends are being over marketed. Google the article "Ice Melt Blends - Right and Wrong Reason to Buy" for more detail on how to buy ice melt blends.
