Abstract:
A composite is characterized by particulates of sand wherein at least a portion of the surface of the particulates is coated with a polycationic polymer. The presence of the polycationic polymer on the surface of the particulates reduces the amount of dust generated during handling and use of the sand. The polycationic polymer further reduces the amount of dust generated during transport of the sand as well during manufacture, treatment or processing of the sand.
