Abstract
A sealing material includes a polyvinylchloride type resin as a major ingredient, a plasticizer, a thixotroping agent, a powdery filler, an adhesive promoter, and a heat stabilizer, and has a viscosity at the low shearing speed of 12,000 to 20,000 cps and a ratio of the viscosity at the low shearing speed to the viscosity at the high shearing speed of 1.5 to 2.5. The sealing material is suitably applied to gap between steel plates joined to each other by a non-contact way. Preferred polyvinylchloride type resin is a blend of a particulate resin having a mean particle size of 2 to 3 .mu.m mixed with a particulate resin having a mean particle size of 20 to 30 .mu.m at a mixing weight ratio of 1:1 to 3:1. Preferably, the plasticizer is a high molecular plasticizer, and the powdery filler is one having an oil absorption of 40 to 50 cc/100 g.
