MAGNESIUM CHLORIDE
Magnesium Chloride is considered (by some) as the best total ice-melter that corrodes metal surfaces less, protects concrete from spilling more, is less toxic and environmentally safer than Calcium Chloride and Sodium Chloride (rock salt).
Benefits
- MAG is less irritating to the skin.
- MAG corrodes metal surfaces less.
- MAG is safer around vegetation.
- MAG is safer on concrete.
- MAG is safer for use around animals and humans.
- MAG is environmentally friendlier.
- MAG is safer and tracks less than Calcium Chloride.
- MAG Brine is an effective road salt prewetting agent.
- MAG is an effective tennis court conditioner.
- MAG can be used for tire ballasting.
MAGNESIUM CHLORIDE (Flake)
Description: Large, flat, clear to off-white flakes containing over 51% water of hydration.
Relative deicing speed: Starts about as fast as calcium chloride, but may become diluted and ineffective.
Lowest practical temperature: Down to 5° F.
Effect on concrete: Chemical attacks concrete at a “slow rate”. Can cause damage from freeze-induced expansion pressures by increasing number of freeze/thaw cycles.
Effect on vegetation: Used as recommended, will not harm vegetation. However, magnesium chloride, on a percentage basis, contains 17 - 56% more chloride ion that other “salt” type deicers.
Residue: Leaves no powdery residue.
Manufacturer’s recommended application rate: Below.
Comments: Flake magnesium chloride contains over 51% water. It starts deicing almost as fast as calcium chloride but may become diluted and ineffective. *”Slowly” attacks concrete chemically.
*Reference for “slow” rate of concrete attack per American Concrete Institute, ACI 201 2R-92, Guide to Durable Concrete.
DUST CONTROL - HOW TO APPLY:
On unpaved roads, construction sites and parking lots:
MAG should be applied on the basis of up to 2 lb/sq. yard, and reapplied at 50% of this rate when the surface appears dry. Road surfaces should be graded prior to MAG® application.
On tennis courts or recreation fields:
MAG should be applied on the basis of up to 1 lb/sq. yard, and reapplied at 50% of this rate when the surface appears dry:
