This Waterproof Electrical/Electronic Spray by Nano Protech looks amazing. Not exactly sure I understand how it works though. At first I thought it sealed the electronics but they demonstrate a socket and light bulb still operating after they are coated and then screwed together. Obviously the coating isn’t an insulator since the bulb is still making contact and it isn’t a conductor since it isn’t shorting out. I would be curious if they salted up that water well if the results would be the same since I am not certain that a light bulb socket would arc in distilled water? I wonder if the coating is simply being scratched through by the contacts on the bulb to make the contact.
“Based on a new kind of nano-zeolithe-technology with a slightly oily consistency, the coating crawls under rust, oxidations and humidity, forming a three dimensional multifunctional protective barrier network at the interface. Fills micro cavities (in circuit boards, micro circuitry, electric coils etc.). Powerful capillary effect allows the product to penetrate inside the blocks without dismantling. Excellent water repellent properties and low surface tension allow it to form a thin protective coating penetrating under the water layer. After spraying, a protective coating forms on the surface. NANO PROTECH provides a 100% water extrusion rate within 10 seconds.”
