MAG is a high performance ice melter that effectively melts snow and ice immediately at temperatures as low as -25oC. MAG is less corrosive, less toxic and environmentally safer than salt and calcium chloride ice melters. Benefits - MAG starts working immediately - MAG works at colder temperatures as low as -25°C / -13 °F - MAG is safer for plants - MAG is safer for pets - Mag is safer for people - MAG is less corrosive to metal and concrete - MAG can also be used for dust suppression on dirt roads, horse riding arenas and for ball diamonds, and to condition tennis courts MAGNESIUM CHLORIDE (Flake) Description: Large, flat, clear to off-white flakes. Components CAS # % by Weight Magnesium Chloride Hexahydrate 7791-18-6 100.0% Relative deicing speed: Mag starts to melt immediately. Lowest practical temperature: MAG works at colder temperatures as low as -25°C / -13 °F Effect on concrete: Independent tests conducted by the National Research Council’s Strategic Highway Research Program (SHRP) show that Sodium chloride (rock salt) caused 63 times more chipping and scaling than MAG.Testing also showed that calcium chloride was better than rock salt but still caused 26 times more chipping and scaling on concrete than MAG® .Two additional Independent tests conducted by the Virginia Department of Transportation and the Swedish VTI confirm SHRP’s findings that MAG® is significantly safer on concrete. Effect on vegetation: Magnesium chloride is used as a plant nutrient in agriculture, Magnesium is the key element in chlorophyll and plays a vital role in photosynthesis. Residue: Leaves no powdery residue. Manufacturer’s recommended application rate: Below. 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.
