Abstract: An encapsulated particle including a core particle, a base layer, and an outer layer is provided. The base layer is disposed about the core particle and comprises polycarbodiimide. The outer layer is disposed about the base layer and comprises wax. A method of forming the encapsulated particle including the steps of reacting an isocyanate in the presence of a catalyst to form the polycarbodiimide, encapsulating the core particle with the polycarbodiimide to form the base layer, and encapsulating the base layer with the wax to form the outer layer is also provided.

Abstract: A dust suppressing aggregate includes a core particle and a dust suppressing agent. The dust suppressing agent comprises polycarbodiimide and is disposed about the core particle for suppressing dusting of the core particle. A method of forming the dust suppressing aggregate includes the steps of reacting isocyanates in the presence of a catalyst to form the polycarbodiimide and encapsulating the core particle with the polycarbodiimide to form the dust suppressing agent. A system for producing the dust suppressing aggregate includes the core particle, the isocyanates, and the catalyst.
