General Information:

What is WaterBlock™?
HzO’s WaterBlock™ is a uniquely hydrophobic and invisible nanocoating that protects whatever it is applied to from the harmful effects of contaminating particles, humidity and, of course, water. For more information on its characteristics and benefits, visit the “What is WaterBlock™?” page -
How can I get WaterBlock™ on my device?
We are not coating aftermarket consumer devices right now, so you can’t send us your phone, tablet, computer, etc. and have it coated at this time. -
Why are you only working with manufacturers? Aren’t you missing out on a major market opportunity now by not coating consumer phones?
There are two big reasons why we think it’s important to integrate WaterBlock™ directly into the manufacturing process: One, by integrating WaterBlock™ technology directly into new devices it eliminates the extra costs and hassle of secondary forms of water protection. You don’t have to ship your phone to have it protected or buy a bulky, awkward case if the technology is already built in! Two, with HzO’s WaterBlock™ integrated into the new technology coming directly from major manufacturers, we are working directly with the people making your device, ensuring that the WaterBlock™ process is customized individually for the best possible results. -
What is WaterBlock™ made of?
HzO’s WaterBlock™ is comprised of a proprietary formula that is lightweight, non-toxic, and nearly invisible. For more information on its charcters and benefits, visit the “What is WaterBlock™?” page. -
Where did WaterBlock™ originate?
You can find out more about the beginning of both HzO and our WaterBlock™ technology on our History page. -
Will I be able to see or feel WaterBlock™ on my device?
No. WaterBlock™ is nearly invisible, weightless, and only applied to the interior of the electronic device. Basically, you won’t even know it is there until you need it most.
-
Will this make my device waterproof?
In short: No. The term ‘waterproof’ is tricky because it implies a level of absolute protection that no current technology, special mechanical seal, or device plug is able to give. Our technology does, however, provide an extremely high level of water protection that is unlike anything else on the market today. WaterBlock™ is a customized nanocoating that protects the internal components of an electronic device from drips, splashes, and full-submersion in water and other liquids and is meant to provide protection against accidental contact with water.

How long will WaterBlock™ last?
WaterBlock™ is an extremely durable substance and will last the lifetime of whatever device it coats. -
How is WaterBlock™ applied?
WaterBlock™ coating is applied through a chemical vapor deposition (CVD) process. Vapors wrap around every intricate part of the electronic assembly including tight passages and crevices in the device architecture. Proprietary equipment engineered by HzO enables coating on a mass production scale that can keep up with the demand of manufacturing.
-
How durable is WaterBlock™ in liquids other than water?
WaterBlock™ has been tested in a number of substances: fresh water, salt water, coffee, soda, and even acid. So far, our coating has handled all tests extremely well and demonstrated very little breakdown in all substances tested. See for yourself in this video.
-
Does WaterBlock™ still perform at high temperatures?
WaterBlock™ is stable from -196°C to 120°C with ambient temperature and pressure. Because our nanocoating doesn’t trap any extra heat, it is safe to use on delicate electronic circuitry. -
Does WaterBlock™ meet IP standards?
Because the Ingress Protection Standard only measures the amount of protection provided against water entering a device, this standard really doesn’t apply to what we are doing with WaterBlock™. HzO’s WaterBlock™ protects whatever it is applied to, while still allowing water to penetrate the device, going against the definition of ‘ingress’ itself. Currently, there is no market standard to measure the sort of unique protection that WaterBlock™ provides, so to fill this gap HzO is currently developing the “WaterBlock™ Standard,” which will measure the amount of protection provided by similar coatings based on time, depth, temperature, and environment.
Investors/Distributors/Other Questions:
-
Can I be an official distributor of WaterBlock™ technology?
HzO does not currently sell its technology through individual distributors. We deploy a business model where we directly interface with major manufacturers. -
Can I buy HzO stock?
HzO is a private company capitalized by a small number of institutional and corporate investors. We are well capitalized and not currently seeking additional investors at this time. -
What is HzO’s relationship with ZAGG?
ZAGG saw the potential in HzO initially and acquired majority rights to our WaterBlock™ technology back in 2009. By August 2011, HzO raised equity capital, established its own board of directors and executive management, and launched to operate autonomously. Today, ZAGG remains a significant shareholder in HzO and supporter of HzO’s future endeavors. -
Can you name some of the big companies HzO is working with?
We maintain a strict level of confidentiality with our customers. HzO is in talks with several major consumer electronic device manufacturers as well as various other manufacturers to bring WaterBlock™ protection to an assortment of electronic devices.
