Description

technical field [0001] The invention relates to the technical field of conductive coatings, in particular to a scratch-resistant conductive coating. Background technique [0002] Conductive coatings generally contain matrix resins, solvents and conductive substances, which can form a conductive coating on a substrate (such as a high-resistivity polymer material). The conductive substance in the coating can conduct current, eliminate the accumulation of static charges, and shield Electromagnetic radiation. When the surface of electronic products is coated with conductive paint, on the one hand, it can prevent the electromagnetic wave radiation in the environment from interfering with the signals of electronic products, so that the signals of electronic products are fidelity and stable; on the other hand, it can prevent electronic products from polluting the environment by electromagnetic wave radiation , to keep the signal of electronic products confidential. Conductive coa...
