Patent ID: 8891154

Claim:
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 positioned between the first and second substrates which comprises: at least one solvent; at least one anodic material; and at least one cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic; and wherein; at least one of a seal member, the first substrate, the second substrate, and the chamber comprises a two-part plug associated with a fill port, and the two-part plug comprises a first sub-component comprising a resin or mixture of resins that are at least one of substantially insoluble and substantially immiscible with the electrochromic medium while in the uncured state, and a second-subcomponent comprising a resin or mixture of resins that exhibit at least one of desired permeability, adhesion, and stability characteristics.
