HZO is a water proofing method of thin film nano coatings for devices of all types. Chris Weed dunks a cell phone in a fish tank at CES to demonstrate the protection HZO provides. The company promotes hydrophobic coatings for electronics.
The company sells to enterprise customers, such as Oxywatch which checks for heart rate and O2 in the blood. HZO protects the internal circuitry, power supply, and all. Another device under their care is Navelite, a compass used by the military according to another HZO representative at CES.
Tag Heuer phones are also on the list of beneficiaries of their technology. For their CES demo, HZO purchased an iPhone 5c, tore it down, and incorporated their protective layer.
