MAG® has less chlorides available for pollution
A major environmental concern is the amount of chlorides added to our lakes, rivers and reservoirs. As shown on the following chart, MAG® has significantly less chlorides available for runoff.
MAG® has 22%, 29%, 39% and 43% less chlorides than potassium chloride, calcium chloride 77%, calcium chloride 90% and sodium chloride respectively. Clearly, MAG® is the environmentally safer choice for high performance ice melters.

MAG® is Less Damaging to Concrete Than Calcium Chloride and Sodium Chloride
All ice melting chemicals lower the freezing point of water and increase the number of freeze/thaw cycles. As a result of water repeatedly freezing and expanding, concrete surfaces will tend to spall, scale or break into small chips. New concrete surfaces and concrete of poor quality are particularly vulnerable to spalling. (Ice melting chemicals should not be used on concrete less than one year old.) As shown below in tests performed by the Strategic Highway Research Program (SHRP), National Research Council, Washington, D.C., the use of MAG® as an ice melter resulted in significantly less concrete spalling than calcium chloride or sodium chloride.

3% test concentrations of brine were used since ice melter brine typically dilutes itself to this level soon after it is applied. After 15 freeze/thaw cycles, the use of sodium chloride resulted in over 63 times and calcium chloride resulted in over 26 times the amount of concrete loss than MAG®.

MAG® Corrodes Tin And Aluminum Less Than Calcium Chloride and Sodium Chloride
Corrosion by ice melters does untold damage to metal surfaces and structures. Tests by the Kali Forschungs Institute in Germany, summarized in the charts below, show that MAG® produces significantly less corrosion than calcium chloride and sodium chloride.
