MG Chemicals 838AR-P - Carbon Conductive Pen
838AR-P pen dispenses an acrylic lacquer pigmented with conductive carbon. The cured traces are durable and corrosion resistant. They adhere well to plastics and most electronic substrates. The traces are flexible, but the product works best on a smooth, flat, hard surface. The valve tip opens when pressed against the surface, and the flow is controlled by squeezing the barrel. This pen repairs traces on keyboards, game controllers or remote controls. It is also good for making small connections, such as jumpers, through-holes, bridges, and links. It is great for drawing resistors too, and it can be used to increase the surface area of contacts by painting the area around them. Use this pen when high conductivity is not required. For applications requiring lower resistance, use the 841AR-P Nickel Conductive Pen or the 842AR-P Silver Conductive Pen.
