Radio-opaque adhesive/sealant for void detection

摘要

A method and structure for providing radio-opaque polymer compounds for use in metal bonding and sealing. A powder filler comprising a high atomic number metal or compound thereof is incorporated into a polymer compound to render it more radio-opaque than the surrounding metal structures. Voids or other discontinuities in the radio-­opaque polymer compound can then be detected by x-ray inspection or other non-destructive radiographic procedure.
