Abstract
A deicer comprises a mixture of a deicing agent, a pre-wetting agent, and a leaching inhibitor. The leaching inhibitor results in decreased liquid migration within and out of a mass of pre-wetted deicer. The deicer can include a deicing salt such as sodium chloride, a pre-wetting agent comprised of magnesium chloride, and a leaching inhibitor such as xanthan gum. The deicer can also include a corrosion inhibitor and/or radiation absorber.
Claims7
A liquid deicer to be used for deicing, anti-icing, and deicer pre-wetting applied to roads and other surfaces, comprising a mixture of;
- a leaching inhibitor, wherein the leaching inhibitor comprises xanthan gum and wherein the leaching inhibitor comprises an effective amount sufficient to produce a liquid agent having a viscosity between about 300 and about 10,000 centipoise at 25 degrees Celsius;
- and
- between about 10 and about 60 percent by weight of a pre-wetting agent, wherein the pre-wetting agent comprises an aqueous solution of sodium chloride, calcium chloride, magnesium chloride, potassium acetate, calcium magnesium acetate or a combination thereof.
