Abstract
A hydrophilic powder such as silica, adapted for dispersion in organic solvents and polymers, is provided with a coating over the outer surface of the powder particles to modify the surface characteristic from polar to non-polar or organophilic, whereby the thus coated powder is readily dispersible without agglomeration or enlargement of the powder particles. Preferred are nano-sized powders.
