Abstract
An electrochromic variable reflectance mirror for a vehicle includes a front element and a rear element. A seal is provided to sealably bond the elements together in a spaced-apart relationship to define a chamber, and an electrochromic material is disposed in the chamber. The seal comprises an epoxy resin cured with a cycloaliphatic amine. The cycloaliphatic amine may be a bis(cycloaliphatic) amine, or more specifically, bis(aminocyclohexyl) methane (PACM). The epoxy resin may be an epoxy novolac resin such as an epoxy phenolic novolac (e.g., DEN431) or an epoxy cresyl novolac resin, a bisphenol A epoxy resin, a bisphenol F epoxy resin, a tetraglycidyl methylenebisbenzenamine, or a glycidyl benzenamine.
