An afterglowing transparent material is produced by the vulcanisation and cross-linking of a mixture containing 65-80 parts by weight of a silicone rubber, 0.5-1 part by weight of a cross-linking agent, 15-30 parts by weight of an after- glowing or luminous powder and 2 to 5 parts by weight of silicone oil or a silicone rubber base polymer, optionally with additives such as organic silane and highly active silica. The material is preferably moulded in the form of wall cladding elements with a thickness of 1 to 5 mm and may be used for signs or emergency lighting. The silicone rubber may a polysiloxane and silicic acid and the phosphors ZnS or CdS. According to whether the composition is hot or cold vulcanising, the silicone oil may be a vinyl alkoxy silane or methyl triacetyl silane. |
