Deicing Products > Commercial > Cryotech CMA®
A number of laboratory tests suggest that CMA may be used as an effective corrosion inhibitor when combined with salt. Although tests were different in type and duration of exposure, all indicated that a minimum of 20% CMA is needed in a CMA/salt blend to provide acceptable corrosion protection. Testing at 20% CMA and 80% salt resulted in a 70 to 80% reduction in corrosion over testing with pure road salt (sodium chloride). The best corrosion protection results from the use of pure CMA.

In order to receive the maximum corrosion protection benefit from CMA deicer blends, it is important to verify the amount of CMA being used in the mixture. Cryotech CMA® is the only commercially available pure calcium magnesium acetate produced and sold in the United States. This product is often blended with other chloride deicers and marketed as "Containing CMA" when it actually contains only a negligible amount of pure CMA. Below are examples of how to insure you are receiving enough pure CMA in your deicer blend.
-Read Labels Closely: Many products state they are made with CMA yet only contain 1-2% CMA and the rest of the mixture is chloride-based. This small amount of CMA would be ineffective in stopping corrosion.
-Ask Questions: Your distributor should be able to provide the exact amount of each ingredient in the deicer blend to ensure you are receiving an adequate amount of pure CMA.
-Double-Check Pricing: If one price quote is much lower or higher than the others, be sure to ask the above questions to verify the same amount of CMA is being used in all products.
Customers also need to be aware that some products claim they contain CMA or calcium magnesium acetate but they actually contain a physical blend of calcium acetate and magnesium acetate. Cryotech CMA® is a patented formulation and each particle contains a specific ratio of calcium and magnesium. It has undergone significant testing to show it is safe for concrete.
