Abstract
A method for applying halide brine to surfaces requiring protection against freeze conditions, inhibition of snow and ice accumulating, deicing or freeze retardation, for example, or dust control with limited corrosion is disclosed, the method comprising the steps of forming an admixture of polyhydroxy carboxylate and polyalkoxylated amine dispersed in an halide brine solution in an amount effective to inhibit corrosion; and applying the admixture to surfaces. The method of this invention can be used to limit corrosion in the application of a halide brine to surfaces of dust-producing materials as well as surfaces requiring protection against freeze conditions.
