METHOD AND COMPOSITION FOR DUST CONTROL

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 separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around.
