Our company develops and sells a nano-waterproof coating that is transparent, non-toxic, environmentally friendly, and odorless. The coating is approximately 2-5 micrometers thick on the product, almost invisible to the naked eye. It is low-cost and has excellent waterproofing effects. After use, it can protect PCBAs from moisture, dampness, sweat, and salt spray corrosion, significantly extending the lifespan of PCBA boards. It solves the problem of PCBAs short-circuiting or even burning out due to accidental water contact, sweat from running, or rain.
By immersing high-density electronic components, PCBA circuit boards, and connectors in Shenzhen Zhongfu Fluere solution for 3 seconds and then removing them for 3 minutes, a dense coating with a thickness of 0.1-10µm can be rapidly cured. Generally, it can pass IPX6, IPX7, and IP67 waterproof tests, as well as 160° water droplet angle superhydrophobicity, double 85, sulfur resistance, high and low temperature tests, and 2000 hours of neutral salt spray testing. It is easy to use, low-cost, and enables large-scale rapid production and application, representing a novel precision electronic protection nanotechnology application solution.
