Cryotech CMA® solid commercial deicer is granulated calcium magnesium acetate, a patented chemical formulation from dolomitic lime and acetic acid. It is identified as a low corrosion, environmental alternative to road salt by the U.S. Federal Highway Administration. CMA is used worldwide to answer environmental concerns and solve problems associated with corrosion and concrete spalling.
CMA is produced as a spherical pellet using Cryotech's patented Unipel technology. This configuration minimizes dust, reduces compaction in storage and results in even spread patterns. Unipel technology and the unique composition of CMA increases product stability for long-term bulk storage.
Potential CMA customers typically include, but are not limited to, DOT's; public works agencies, property management firms, industrial firms, and construction companies. Customers concerned with corrosion, deicing performance, and environmental issues choose CMA as an effective solution to their concerns.
CMA is best used as a deicer, spread on the pavement after precipitation starts. Effective to the same temperatures as road salt, CMA has many unique performance characteristics. CMA can be used to offset the corrosive effects of chlorides while enhancing deicing performance when blended with road salt at rates greater than 20% CMA by weight. It is available from Cryotech in a 40% blend as Cryotech CMA40® solid commercial deicer.
CMA is also used in liquid form, generally for anti-icing roads and bridges. The fluid is applied prior to a storm to prevent snow and ice from bonding to the surface. Liquid CMA is typically formulated in the field from dry CMA. Contact Cryotech for mixing instructions.
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 by checking labels and product data sheets. Cryotech CMA is the only commercially available pure calcium magnesium acetate produced and sold in the United States.
