Abstract:
An electronic device and a method for predicting water ingress employ a water damage indicator including a water-dispersible coating layer which includes a water-dispersible, radiation-cured polymer. Electronic components of the device, which may be susceptible to water damage, are disposed within a casing. The water damage indicator may contact the casing of the electronic device and/or the electronic components. When water enters the casing, the water dispersible coating layer is at least partially removed, revealing the surface beneath, thereby providing an indication of potential water damage to the electronic components. The water damage indicator is not readily replaceable after manufacture, making it more difficult for a customer to disguise potential water damage to the device.
