Abstract
This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are wax-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.
