Volatile corrosion inhibitors (VCIs) in emitters have been developed and studied. Building on a basis of chemistries that have worked well for industry over decades, VCI formulations were developed for the emitter. Accelerated corrosion studies (temperature and humidity cycling) showed excellent protection for a large variety of metals in presence of VCIs. Experiments were also performed to select a tape suitable for adherence of the emitter to a broad choice of substrates. Finally, some application case histories where the VCI emitter has been used successfully to provide corrosion protection are presented.
