Since then we had someone reach out asking if we could coat their phone so they could swim with it. That is a bit ambitious, and definitely not something we recommend. These coatings are designed to effectively waterproof against incidental contact with water. Our more robust coatings 7.0 and 8.0 provide waterproofing up to IPX7 level, which was basically demonstrated in the Guinness video. But the technology isn’t there yet for these devices to be 100% waterproof for their entire lifetime.
Our coatings don’t stop water from getting in the device. Our coating allows water into the device but protects the electrical components (the PCB). So my humble advice, although we can keep your phone alive for 30 minutes underwater or (underbeer), I would recommend just going ahead and taking it out immediately if you drop it in liquid.
This morning, we released a video. I may or may not play a small role…
NanoProof 8.0 is typically used to waterproof – you know, against dropping in the pool or a toilet. But fear not, because we now have proof that your phone will be just fine if you drop it in a pitcher of beer as well! While the test doesn’t meet the strict requirements of IPX7 level waterproofing, we did submerge it for 30 minutes in the container of Guinness Extra Stout. For the life of me, I can’t figure out why you wouldn’t just take it out immediately if you dropped it in a pitcher, but I guess Guinness can do crazy things to your cognitive functioning! So we left it in there for 30 minutes to account for those times when you need to write a short novel before attempting to dry your phone. So here is NanoProof 8.0 in all of its glory.
Conformal coatings and expensive parylene vacuum deposition equipment have always been the only solutions for making electronic devices impervious to liquids. The market was missing something, though. We wanted to develop a product that required no equipment and allowed easy rework throughout the PCB manufacturing process. It needed to be incredibly easy to apply and offer a range of waterproofing levels to meet unique project requirements.
Well it seems like we are fighting a losing battle…..
“Superhydrophobic” has become the common nomenclature to describe ANY surface which easily repels liquids. Sometimes it is used correctly. Most times, however, it is incorrect. A superhydrophobic coating is a coating that has a water contact angle of greater than 150 degrees and a sliding angle of less than 10 degrees.
This is a question that has many different definitions (depending on who you ask), and therefore “levels” of cleanliness from visibly dirty all the way down to free of impurity at the atomic level. How much cleanliness is required depends heavily on the application; knowing what the right level is for surface coatings demands some intimate knowledge of the system being evaluated.
