Replicas are molded by curing a photo-curable liquid silicone rubber composition to form a transparent mother mold having a cavity corresponding to the outer contour of a master model, casting a photo-curable liquid resin into the mold cavity, and irradiating light to the liquid resin through the mold wall. Replicas can be fabricated by simple steps and within a short time.

An electromagnetic wave (EM) absorber is constructed by integrally laminating an EM-absorbing layer having an EM-absorbing filler dispersed in a silicone resin on at least one surface of an EM-reflecting layer having an electrically conductive filler dispersed in a silicone resin. It has satisfactory EM-absorbing and shielding abilities and is workable, flexible, weather resistant and heat resistant due to the nature of the silicone resin itself. The use of the silicone resin in both the EM-absorbing and reflecting layers ensures that a firm bond is established between the layers. In a preferred embodiment wherein a heat conductive filler is blended, the absorber has a satisfactory heat transfer ability as well.

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.
