Abstract
Microsphere beads are mixed with a surface barrier liquid or mixture of such a liquid with a solid effective to prevent agglomeration and surface bonding of the microspheres; by the control of the application of heat and balancing temperature and active mixing, removal of water from the microspheres is achieved. The surface barrier liquid or mixture of such a liquid with a solid in the present invention is any one of a wide diversity of materials which meet the requirements of the intended function, i.e., to prevent the agglomeration of the microspheres during the process. Suitable materials include, by way of example, plasticizers, diluents, extenders, monomers and oligomers, and the like.
