CHEMICAL BINDER FOR COATING PAYLOAD IN OPEN TOP HOPPER CARS, TRUCKS, PILES AND SIMILAR STORAGE/SHIPPING CONTAINERS

The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying to the pile a binder coating containing VAE and crude glycerin. The binder coating cures and hardens slowly so it is able to remain flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles and also for piles within and /or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. The coating is effective both when it is flexible and after it cures. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.
