A well treatment composite is characterized by particulates wherein at least a portion of the substrate of the particulates is coated with a polycationic polymer. The presence of the polycationic polymer on the surface of the well treatment particulates reduces the generation of dust and fines during a well treatment operation. The polycationic polymer further reduces the amount of dust or fines generated during transport of the well treatment particulates to a remote location as well during the manufacture or processing of well treatment particulates.
