ProMelt Ultra™ is a high performance de-icing liquid made from a refined corn carbohydrate derivative blended with magnesium chloride. It is a versatile anti-icing, de-icing and pre-wetting agent that delivers unparalleled performance in colder environments.

Features and Benefits

ProMelt Ultra™ de-icer significantly improves the eutectic point and phase change properties of MgCl2. Promelt Ultra inhibited has the extremely low eutectic point of approximately -65o C.

  • Versatile liquid that can be used to anti-ice, de-ice and pre-wet.
  • Superior anti-bonding properties.
  • Reduces bounce and scatter and salt application rates which saves time, labour, fuel and materials.
  • Less corrosive than salt brine.
  • Better for the environment – our magnesium chloride is approved for organic production as a crop fertilizer and soil amendment by OMRI in the US and Canada.

Product Application

ProMelt Ultra™ is specifically designed for anti-icing, direct application de-icing, frost prevention and prewetting of solids. Specific application guidelines are:

  • Anti-Icing
    Application rates of 40 - 70 litres per lane kilometre are typical. Up to 90 litres per lane kilometre should be considered the maximum in any anti-icing situation.
  • Direct Liquid Application De-Icing
    Application rates of 90 - 100 litres per lane kilometre.
  • Frost Prevention
    Application rates of 20 - 40 litres per lane kilometre are standard. These rates can vary depending on storm conditions and service level goals.
  • Pre-wetting
    Application rates from 20-60 litres per tonne of substrate, depending upon the solid used and the performance objective.
