Time variation of receding contact angle on the surface of silicone rubber pieces and that of weight of them were investigated, which had been immersed in water. It was shown that reduction in hydrophobicity in a short time range is an temporal phenomenon. However, repetitive immersion or acceleration by using water at elevated temperature proved that hydrophobicity on the surface of specimens was lost gradually. Time variation of weight of specimens suggested that a certain component like low molecular silicone migrates from the bulk of specimens to their surface.
