Abstract
A dust preventing crust on an exposed surface of a mass of a dusting material is formed from a dried liquid solution of a non-ionic cellulose ether, a surfactant, and water. The strength of the crust is increased by adding a plasticizer to the liquid solution prior to drying the liquid solution on the mass of dusting material. The strength of the dust preventing crust is increased over a strength of a dust preventing crust produced from drying a fluid solution comprising the non-ionic cellulose ether, the surfactant and water prior to adding the plasticizer.
