A method for producing a masterbatch includes continuously feeding a first composition containing an elastomeric latex to a coagulation chamber; and continuously feeding a second composition containing a particulate filler and a salt to the coagulation chamber. The first composition and the second composition are mixed in the coagulation chamber to form the masterbatch. The salt may be provided so that a salt concentration in the coagulation chamber matches that necessary to bring a magnitude of the zeta potential of the latex to be within a range of 30 to 15 mV, 15 to 1 mV, or 1 to 0 mV. The second composition may be fed to the coagulation chamber at a pressure of at least about 300 psig and/or a velocity of at least about 100 feet per second. The masterbatch may be dry mixed with an additional elastomer to form an elastomeric composite blend.
