PCT No. PCT/JP96/02816 Sec. 371 Date Mar. 30, 1998 Sec. 102(e) Date Mar. 30, 1998 PCT Filed Sep. 27, 1996 PCT Pub. No. WO97/12933 PCT Pub. Date Apr. 10, 1997This application provides a heat vulcanizable rubber composition which prevents scorch in a molding process for the production of vulcanized rubber molded articles, and has good storage stability when the composition is formulated in the form of a one pack pasty composition. The heat vulcanizable rubber composition of the present invention contains (A) a rubber component having double bonds, and (B) a vulcanizing agent in the solid state at room temperature and a vulcanizing accelerator in the solid state at room temperature, characterized in that the particle surfaces of at least one of the vulcanizing agent and vulcanizing accelerator are treated with a fine powder having a center particle size of 2 mu m or less in a weight ratio of said at least one of the vulcanizing agent and vulcanizing accelerator to the fine powder in the range between 1:0.001 to 1:2, to form the fine powder-treated vulcanizing agent and/or vulcanizing accelerator. This composition is useful as an adhesive, a sealant, a coating material, and a material for molded articles.
