Sealing method and article |
摘要 |
An article adapted for sealing a discontinuity in a surface. The article includes a melt-flowable composition that flows and seals the discontinuity when the article is heated to a sufficient temperature and a polymeric cap controlling the melt-flow behavior of the melt-flowable composition to substantially confine the melt-flowable composition to the area underneath the cap, when the article is heated to a temperature sufficient to cause the melt-flowable composition to flow, and then cooled.
