Cryotech CMA® is granulated calcium magnesium acetate, a patented chemical formulation from dolomitic lime and acetic acid. It was first identified as a low corrosion, environmental alternative to road salt by the U.S. Federal Highway Administration in the late 1970's. Cryotech, and its predecessor Chevron, then tested and commercially developed the technology. Today, CMA is used worldwide to answer environmental concerns and solve problems associated with corrosion and concrete spalling.
CMA is generally used in a solid form and spread on the surface like other deicers. Although CMA is effective to the same temperatures as salt, CMA has many unique performance characteristics. Therefore, first-time users should review product application guidelines closely. For answers to frequently asked questions regarding CMA, please see the Questions and Answers information sheet.
Often CMA is used as a corrosion inhibitor, blended with road salt at rates greater than 20% CMA by weight. It is available from Cryotech in a 40% blend as CMA40®.
CMA is also used in liquid form, generally for anti-icing roads and bridges. Here, the fluid is applied prior to a storm event 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.
