The faster an ice melter works, the less chance there is for a mishap to occur. That’s why MAC® is powered by the accelerating agent, Activar® and the anti-corrosion additive CMA. MAC® has been shown in Strategic Highway Research Program testing, to exceed the melt value of a theoretical 28% calcium chloride blend.

Ice melt comparisons measured in milliliters using the H-205.1 testing method set up by the SHRP (Strategic Highway Research Program). Ice melters were tested at 15°F for 20 minutes.


Controlled Spreading:

MAC® undergoes a thorough screening process optimizing particle size for controlled spreading. Ossian’s screening process reduces dust, provides more flexibility with spreader settings and reduces cost, allowing you to melt more with less product. MAC® contains an anti-caking agent to ensure easy flow for ice melt spreaders and longer storage life.

Safe for Concrete and Vegetation.

MAC® will not harm concrete and vegetation when used according to label instruction. Incorporating liquid anti-icing practices with dry application rates is essential to reducing chloride and salt impacts on the environment.

Application Directions:

Spread product evenly over icy surface, using a cup, scoop or spreader, at a rate of 1/4 to 1/2 cup per square yard. DO NOT PILE. When melting has occurred and ice separates from the surface, remove slush and water to prevent refreezing. In snow deeper than two inches, all de-icers are impractical. Shovel first, then spread MAC® to melt any ice or hard packed snow left behind. Ice melters are not to be used to replace shoveling. Over application can be damaging to landscape and does not create a safer surface.
