Abstract
The silicone rubber adhesive film of the present invention is characterized by simplicity of handling and an excellent workability and useablility, as well as by adhesiveness for various types of substrates and an excellent durability of adhesion. These characteristics are obtained because the silicone rubber adhesive film of the present invention comprises a silicone rubber composition which consists of components (A) through (G), particularly the specific wet-method hydrophobicized reinforcing silica comprising component (C) and the specific compounds of components (D) and (E) or components (D), (E), and (F), and because the tensile strength of said uncured silicone rubber composition falls within the range of 1.5 kg/cm.sup.2 to 5.0 kg/cm.sup.2 at 25 degrees Centigrade (JIS K 6301). Accordingly, when used on flat substrates such as textiles, glass, rubber sheet, etc., it can tightly bond the adhered partners into a single, integral body.
