Abstract
An electrochromic device including: (a) a first substantially transparent substrate having an electrically conductive material associated therewith; (b) a second substrate having an electrically conductive material associated therewith; (c) an electrochromic medium contained within a chamber positioned between the first and second substrates which includes: (1) a solvent; (2) an anodic material; and (3) a cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic; (d) wherein a seal member, the first substrate, the second substrate, and/or the chamber includes a plug associated with a fill port; and (e) wherein the plug is at least partially cured with an antimonate photo initiator and/or is one- or two-part plug which comprises a resin or mixture of resins that are substantially insoluble and/or substantially immiscible with an associated electrochromic medium while in the uncured state.
