Abstract
A thermosetting highly foaming sealer of this invention contains an unvulcanized rubber, a vulcanizing agent, a softener and an inorganic filler. It is bonded on one of two parallel planes forming a gap, and is vulcanized and foamed by heating to fill up the gap. A feature of the thermosetting highly foaming sealer is that it comprises a first sealing member bonded on one of two parallel planes before heating, foaming and expanding from 1 to 2 times of original volume thereof when vulcanized by heating, and a second sealing member laminated on the first sealing member foaming and expanding 6 times or more of original volume thereof when vulcanized by heating. Accordingly, the thermosetting highly foaming sealer of this invention can securely fill the gap without running down or slipping off even when it is provided on a vertical plane, thereby preventing dusts and water from intruding from environment. The thermosetting highly foaming sealer thus shows a good rustproofing capability as well.
