First Claim
1. An electrochromic device, comprising:
- a first substantially transparent substrate having an electrically conductive material associated therewith;
a second substrate having an electrically conductive material associated therewith;
an electrochromic medium contained within a chamber defined by the first and second substrates and a seal member joining the first and second substrates;
wherein;
at least one of a seal member, the first substrate, the second substrate comprises a fill port;
the fill port comprises a plug; and
the plug comprises the reaction product of an epoxy resin, at least one photoinitiator and at least one photosensitizer.
