摘要： Embodiments of the present invention include de-icing compositions, along with the manufacture of and use of the de-icing compositions. The de-icing compositions achieve a higher melting capacity and melt ice for longer times than conventional de-icing solutions. The de-icing compositions include suspensions of salt instead of solutions. These de-icing suspensions can be applied to ice using liquid application systems. Embodiments include a de-icing composition. The de-icing composition is a suspension. The de-icing composition includes a solvent, which includes water. The de-icing composition may also include a salt component in a total concentration greater than the solubility of the salt component in water at a temperature in a range from 0° F. to 40° F. A portion of the salt component may not be dissolved in the solvent. The undissolved portion of the salt component may include particles with an effective diameter less than 500 μm. The de-icing composition may further include a suspending agent.

摘要： According to the invention, a melting and traction matrix for use on icy or wet surfaces comprising at least one melting agent and at least one substrate impregnated therewith and a method for making and using same are disclosed. The matrix is applied to surfaces where ice is present or anticipated. Upon surface contact, the substrate provides immediate traction and melting agent dissipates from the substrate. Further melting agent dissipates slowly by diffusion for a long-term, persistent effect, in combination with the substrate, the overall amount of melting agent may be controlled, thereby mitigating potential corrosive, toxic and adverse cosmetic and/or environmental effects. The remaining substrate after melting agent has totally diffused may provide longer traction benefit or may be swept away.
