Frequently Asked Questions
Sullivan Corporation is the exclusive distributor of Cryotech products in the state of Michigan.
What is CMA?
CMA is a simple combination of dolomitic lime and acetic acid (a principal component of vinegar) and is produced at Cryotech's manufacturing facility in Fort Madison, Iowa.
Why was CMA developed?
There has long been a concern for damage to the environment and to structures like bridges and parking garages caused by the use of chloride deicers. In the 1970's, the Federal Highway Administration (FHWA) identified calcium magnesium acetate as the only low-corrosion chemical alternative to road salt that also protected the environment. Years of research and field applications have proven CMA is no more corrosive than tap water and does not harm vegetation or receiving waters.
Why blend CMA and sodium chloride?
Laboratory studies have shown that CMA, when mixed with sodium chloride at a minimum 20%, by weight, inhibits salt's naturally corrosive properties to exposed steel. The more CMA in the blend, the better the corrosion and concrete spalling protection.
What can I do to be sure I am purchasing the correct blend?
Read Labels Closely: Many products state they are made with CMA yet only contain 1-2% CMA, by weight, 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 pellet contains a specific ratio of calcium and magnesium. It has undergone significant testing to show it is safe for concrete.
What is the difference between DE-ICING & ANTI-ICING?
 Deicing is a measure where a deicer is applied to the top of an accumulation of snow, ice or frost that is already bonded or formed to the pavement surface. This is a reactive approach.
Anti-icing is a snow and ice control measure to prevent a strong bond between frozen precipitation or frost and a pavement surface by timely application of a chemical freezing point depressant. This is a proactive approach.
