Conductive paint is used for hand-made tracks, circuits and buttons, as well as joining electronic components and repairing printed circuit boards. The base for creating such substance is usually polyurethane, epoxy, acrylic or water-based paint, which is filled with conductive particles - nickel, silver or graphite and active carbon. Conductive paint is durable (even several years) and can be applied to a variety of materials - including paper, wood, plastic, glass, textiles and other plastics.

Conductive paint properties
Conductive paint dries within 10 to 15 minutes after application and is easily washable with soapy water. It can be protected from the outside with an acrylic lacquer, for example - this will not adversely affect the conductive properties. The paint can be applied to paper, wood, plastic, cardboard, fabric and many other materials. Most polyurethane or acrylic conductive paints are non-toxic and do not produce harmful fumes, so they can also be used during technical activities with children.
Use of conductive paint
Conductive paint can be used to create and repair paths on printed circuit boards and other materials, connect electronic components, and make touch or proximity sensors and switches. It can also be used for temporary repairs (such as wiring) and cold soldering. Conductive paint will also work well for joining so-called e-materials, i.e. conductive fabrics that are designed to create smart clothes controlled by microcontrollers.
How to use conductive paint?
Before use, make sure the surface to which the paint is to be applied is clean and dry. Conductive paint can be applied with a brush or directly from the package if it is equipped with a suitable applicator. If paint is used to connect electronic components, you must make sure that their contacts are thoroughly covered (and that the paint covering the contacts connects sufficiently to the rest of the path) - otherwise the conductivity may not be strong enough for the entire circuit to work as expected.
