Cryotech CMA® - Solid deicer
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. Today, CMA is used worldwide to answer environmental concerns and solve problems associated with corrosion and concrete spalling.
Typical CMA customers are concerned with concrete spalling, corrosion or environmental issues. They include transportation agencies, military installations, universities, property management firms, and commercial facilities. They require the performance of a solid deicer without the risk of negative environmental impact or infrastructure damage generally associated with chlorides and urea. For these reasons, CMA is often specified by design engineers for use on bridge decks, parking garages and sidewalks, and by operation managers to solve environmental problems such as ground water contamination, soil compaction and vegetation burn.
Benefits
- Low corrosion: less corrosive than tap water
- Safe for concrete: the safest deicer for concrete
- Excellent inhibitor: reduces chloride corrosion
- Safe for the environment: biodegradable, low toxicity
- Residual effect: requires fewer applications
- Multi-purpose: use straight, with salt, with sand, or as a liquid
Performance
- Has long lasting effect - better than salt or urea
- Breaks/inhibits bond between snow/ice and pavement
- Creates a dry, powdery snow which improves traction
Application
- Apply early in the storm to prevent snow/ice bonding
- First application:
- Commercial 50-150 g/m²
- Highway 50-150 g/m²
- Anti-icing:
- Commercial 75-100 g/m²
- Highway 20-40 g/m²
- Wait at least 20 minutes to remove snow/ice
- Re-apply when new snow/ice accumulation shows first tendency to pack (bond)
Environment
- Biodegrades to CO2 and H2O
- Calcium and magnesium increase soil permeability
- Essentially non-toxic to aquatic species
- Poor mobility in soil - unlikely to reach groundwater
- Does not contain nitrogen, sodium or chlorides
- Safe for vegetation
Handling
- May be stored indefinitely if kept dry
- Take care to avoid caking caused by excess moisture
- Excessive handling may cause dustiness
