ABSTRACT:
The specification discloses a defrosting mirror especially adapted for outdoor use such as on the exterior of vehicles. The mirror includes an electrically conductive, resistive coating applied to a surface of a light reflective mirror element. The coating includes micro-sized graphite particles dispersed throughout a resinous binder material such that electricity flows through the coating to generate heat which is transferred to the mirror element. A resinous primer layer intermediate the coating and mirror element bonds the coating to the mirror element for retention of the conductive, resistive coating especially when the mirror is exposed to humidity, salt spray, or other environmental or weather conditions.
