Abstract
A silicone rubber composition for use in rubber construction materials contains dispersed particles having a photocatalytic activity. The particles are surface-treated with a compound that can easily be deteriorated by the photocatalytic activity under outdoor exposure to ultraviolet light. Rubber construction materials made of the cured form of the composition, when exposed to ultraviolet light, undergo surface hydrophilization that endows them with excellent stain resistance, and also have excellent sealing properties. When the composition is applied as a coating, filled into joints, or used as a solid gasket, it does not cause staining of the building, joints, or the area around joints.
