If you need submerge a Raspberry Pi underwatera circuit, a cable or any electronic device, Parylene creates a protective layer at a molecular level, which allows it to be used as if it were outdoors.
There are many products, in the form of a spray or for immersion in a liquid, that add a protective layer to an electronic circuit, so that it can be immersed in water and keep it working. But most leave a greasy mark on the hardware or lose their capability over time.
The company HZO presented at CES 2024 a new product called Parylene, which creates a protective layer against water at the molecular level, between 2 and 25 microns thick. It is invisible, does not stain or fade over time.
This is how Parylene, the water protector, works
As it is a protective layer that works at a molecular level, it leaves no space through which water can seep. This is why it is extremely effective.
As can be seen in the opening photo of the news, in a demonstration for Tom’s hardware, HZO immersed a Raspberry PI in an aquarium, along with a USB-C cable and HDMIand I connected them to a monitor placed on a table. The Raspberry Pi worked flawlessly, sending the image to the monitor.

Parylene works with all types of electronic circuits and also with tablets and other devices. It is applied by a method known as chemical vapor deposition (CVD).
First, a precursor material must be heated until it sublimates from a solid to a gas. The precursor gas is further heated to activate and form the reactive monomers.
Inside the deposition chamber, which is at room temperature, the monomers enter and deposit on everything inside. When they fall close to each other, they connect and form the polymer layer. The thickness of this protective film usually varies between 2 and 25 microns..
It is the most effective protective layer against water that exists, at the cost of being offered only on an industrial level The application process takes approximately 15 hours. You need to send the device directly to HZO or purchase a machine that applies it.
With Palyrene you can waterproof any electronic device, even bare circuitry, like a Raspberry Pi. It is an industrial solution designed for submersible equipment or equipment working in high humidity environments.
