Water-Resistant Circuit Boards Might Save Phones that Fall Into Toilets

 |  |  |  |  April 21, 2012

If you can believe it, people drop their phones in toilet bowls fairly regularly. It happens so often that related goods like drying packs and gadget rescue kits have made an appearance in a lot of online retailers.

However, here’s one innovation that will raise the bar when it comes to ensuring the safety and durability of these gadgets: water-resistance coatings for mobile phone circuit boards.

The coating is currently being developed by Daikin Industries, which describes it as a thin film that’s resistant to water and moisture and is environmentally friendly.

The coating dries in one minute at room temperature and takes effect right away, which is pretty impressive.

Daikin says: “We’re suggesting this coating as a way to reduce the risk of phones malfunctioning if they happen to get dropped in water. This product is made by dissolving a fluoropolymer in a fluorinated solvent. The fluoropolymer is nonflammable and has low toxicity. By using this solvent, we’ve achieved a coating that’s environmentally friendly.”
