Non-drying sealer composition |
摘要 |
The present invention provides a non-drying sealer composition which does not substantially swell or shrink non-polar vulcanized rubber products. The non-drying sealer composition is suitable for sealing a gap between a sheet-metal flange and the inside of a trim part by charging the composition into the trim part of the weatherstrip for an automobile. The non-drying sealer composition comprises liquid rubber as a sealer base, a tackifier and a thixotropic agent as auxiliary materials, and a non-volatile softener (including a plasticizer) as a dispersing medium. As the non-volatile softer, a shrinking component is used alone or in combination with a swelling component. Thus the swelling action of the sealer composition against the non-polar vulcanized rubber product reaches within about ±5% in terms of the degree of swelling.
