Both the function of electronic products and the system of electronic industry have developed to a relatively perfect level. Large scale innovation is rare. Micro promotion and micro innovation have become an important way for brands to show their personality and enhance their functions. Waterproof function is an important part of minimally invasive new products, because the components of electronic products will be damaged after water, affecting their normal work, and the waterproof function is to protect electronic products from water damage.

Many mobile phone manufacturers are launching waterproof mobile phones. However, most waterproof mobile phones are waterproof through waterproof membrane, sealing ring and waterproof rubber plug, which leads to the weight and appearance of mobile phones are not ideal and can not meet the needs of consumers, so they are gradually abandoned by people. But some manufacturers use three layers of waterproof coating to achieve waterproof.

With the development of science and technology and the improvement of people's material living standards, consumers put forward higher requirements for product quality. People no longer need simple and crude "Three Prevention" products, but should meet the requirements of environmental protection, health, lightweight and so on. Therefore, we have developed a new type of electronic waterproof material, continuously improved the technology, and successfully developed a special electronic nano waterproof material nano waterproof coating.

It not only has the basic protection characteristics of the traditional three proofing coating, but also solves some problems that can not be solved by the three proofing coating, and greatly improves the protection and environmental protection performance.

Waterproof principle: nano waterproof coating is a kind of fluorine compound solution with waterproof and oil proof performance. The ultra-thin waterproof coating can form a waterproof coating with a thickness of about one thousandth on the electronic PCB.

At the nanoscale, the convex surface can absorb the surrounding gas molecules and form a stable gas film, avoiding the direct contact between the material and water molecules. At this time, the contact angle of water droplets tends to be the maximum, and the electron surface shows super hydrophobic properties. However, its surface pore size is much smaller than that of water molecules, so it is impossible to leak, thus forming a water repellent effect similar to that of lotus leaf. Therefore, it can effectively protect smart electronic components from sweat and rain. In addition, the coating also has the advantages of waterproof, moisture-proof and salt spray resistance.
