Eric’s voice of reason…
I hate to rain on this parade (okay, a little bit of a pun was intended there!) but I want to be a voice of caution here. Sprays that supposedly ‘make electronics waterproof’ have been the content of late-night infomercials for years. ‘Nano-technology’ is just a fancy way of saying that they’re using a chemical (generally some sort of oil) that has water-repelant properties at the molecular level (just like the silicone spray we already use) and perhaps some stuff that causes the chemical to bond with the material it’s applied to
Here are some examples:
CorrosionX, Liquipel, NeverWet, HzO, P2i, … the list goes on.
All of these companies have managed to get sensationalistic press that reads something like “new revolutionary invention changes everything”
Here are some examples:
They work by adding a hydrophobic substance to the surface of a material, but it is just a coating and will not hold up over time if submerged
How do they dunk electronics in water without ruining them? It’s fresh water. Although their spray will help prevent water from accumulating (just like rain-x on a windshield that helps water “roll off” the surface) it’s not actually insulating anything. I could do a similar demo with an electronics board that has no coating on it in fresh water, and as long as the water that’s accumulated on the board were removed afterward, you’d see just about the same results.
There are also ways of actually putting an insulating layer over electronics which is called conformal coating, but even this is not something people would trust while being submerged in salt water.
What’s more, is that even if something like this worked reliably, electrical insulation isn’t our issue with the motors, it’s corrosion on the bearings. Because the bearings used in our motor are made with high carbon (non-stainless) steel, they oxidize over time. Because they are moving parts, any spray or coating wears off.
We’ve already been using a “hydrophobic nanotechnology” to help reduce this process, and it doesn’t cost $150 a bottle. Here’s a link.
Okay- so all of this is a bit harsh, I’ll admit. Sprays and coatings like this one can actually help protect electronics if they get wet accidentally. But I want to disband and claims that they make things anything more then splashproof- especially with moving components. Would you spray your laptop with this stuff and take it scuba diving with you?
I think it’s worth doing some research and experimentation with various chemicals to see how they improve the longevity of things underwater, and getting the discussion going about the topic is a good idea, but our methods and recommendations should ultimately be based on testing
