It is proposed that dispersion of an inorganic in an organic phase, in the presence of titanate coupling agents, is enhanced by the replacement of the water of hydration at the inorganic surface with a monomolecular layer or organo functional titanate causing inorganic/organic phase compatibilization at the interface, thereby increasing the degree of displacement of air by the organic phase in the voids of the inorganic component. Typically, dispersion tests show that 1/2% titanate coupling agent on calcium carbonate will reduce the viscosity of 50% calcium carbonate filled dioctyl phthalate from 177,000 cps to 2,600 cps. When successful coupling and dispersion is achieved through proper processing, new adhesion, property and rheology performance standards of fiber-reinforced pigmented and/or extender filled polymer composites and coatings are possible.
