Conformal Coating is a special synthetic resin combined with a multi-component copolymer modified polymer resin, offering superior insulation protection compared to traditional three-proof adhesives. When applied to PCBs, it forms a dense protective film that shields against moisture, salt spray, mildew, cold and heat shock, aging, radiation, ozone corrosion, and vibration. This enhances the reliability and lifespan of circuit boards, allowing for higher power and closer spacing of components, thus supporting miniaturization. The coating is quick-drying, low-odor, and environmentally friendly, improving production efficiency and quality.
