Features The coating is dark gray, and also contains appropriate amount of oily diluent, coating resin and conductive agent, and has excellent electrical conductivity. The main conductive component of the conductive paint is metallic nic-kel powder. Can be used for circuit board repair, circuit graffiti, e-cards, etc. Some insulating materials can be covered on the drawn circuit, thereby drawing a multilayer circuit. Conductive ink adheres well to commonly used materials and is not easily washed away with water. The paint is highly fluid and can be electrically conductive after being painted and naturally dried. Specification:Condition: 100% Brand New Item Type: Conductive Ink Pen Color: Gold Main Conductive Component: Metallic Nic-kel Powder Instructions: The use of the conductive brush is similar to the use of the correction fluid.
