  • Magnesium chloride and potassium sulfate deicer
    Patent number: 8372302
    Abstract: Deicing compositions comprising magnesium chloride and potassium sulfate are provided. The compositions are pet friendly and have less of a detrimental impact on the environment and vegetation than prior art compositions. Methods of reducing or preventing the build-up of ice or snow on various surfaces are also provided.
    Type: Grant
    Filed: August 19, 2010
    Date of Patent: February 12, 2013
    Assignee: North American Salt Company

  • Deicing blend and method of using the same
    Patent number: 7935269
    Abstract: Novel deicing compositions and methods of using and forming those compositions are provided. The compositions comprise a blend of NaCl, KCl, and MgCl2, with the NaCl preferably being coated with a solution comprising an ice melt trigger and/or urea. The deicing composition has low corrosion, particularly when compared to a NaCl solution. At the same time, the compositions have superior melt properties compared to NaCl solutions as well as other prior art deicers. The deicing compositions are useful for melting ice on surfaces such as roadways.
