Video Roundup: See how HZO compares to other water protection technologies

Posted on July 11th, 2017 by

To ensure our protection is the best solution for our customers, HZO frequently tests our products against other technologies on the market. Occasionally we publish these results to help others see the results for themselves.

HZO vs. Mechanical Seals: 

Mechanical seals, gaskets and other sealing methods are the ‘go-to’ for many designers and engineers, but have seriously drawbacks in this day and age of smaller, thinner, more portable electronics. In the video above, HZO illustrates that while mechanical seals may work out of the box, drops, temperature fluctuations and bends can compromise the integrity of this aging technology. HZO’s internal Parylene coating withstands the bumps and bruises of everyday life and keeps the circuitry it is applied to protected from a wide variety of threats.

HZO vs. Plasma Applied Coatings: 


Plasma applied coatings make a surface hydrophobic, wicking water away from the surface of a circuit board with minimal manufacturing processes. Hydrophobic coatings are not waterproof, but depending on specific plasma applied coating, can offer the protection manufacturers are looking for. They work well to repel water, but prolonged exposure or submersion will destroy the circuitry as seen in the videos above. In our testing, just as all waterproofing isn’t created equal, neither are plasma applied coatings. The coatings filmed above definitely have their limits, but other plasma applied coatings out there have promise to offer protection that brands are seeking.


No solution is perfect, but HZO is pretty close. A microns-thin transparent coating capable of robust protection against a wide variety of liquids and environments is the next generation of waterproofing. HZO already offers mass production solutions for some of the top brands in the world. Reach out today to see how HZO can help protect your upcoming products.
