The surface treatment of the filler with the silane coupling agent(silane agent) is composed of three basic reactions, hydrolysis of silane agent by water, self condensation of silane agent, and the reaction between filler surfaces and silane agent molecules. Because the mechanical properties of elastomer are influenced largely by the filler surface structure formed by silane agent molecules, control of the above mentioned reactions are indispensable to manufacture a elastomer in a constant quality. Effect of the chemical structure of filler surface, adsorbed water on the filler surface and surface treatment condition on these reactions were summarized in this paper. In addition to this, our recent results obtained by atomic force microscope measurement of mica surface, that is, the treatment condition has significant effect on the the structure of the silane agents on the surface of filler, is also introduced.
