Electric Paint is a non-toxic, water-based, water soluble, electrically conductive black paint Apply on any surface that is non-hydrophobic, like paper, card or wood It air-dries at room temperature, and is great for fast prototyping with printed electronics, fixing small repairs in circuits, or painting large interactive murals It can be used in circuits as a painted resistor element, a capacitive electrode or can function as a conductor in designs that can tolerate high resistivity It is intended for applications with circuits using low DC voltages at low currents Apply by squeezing the tube Great for cold soldering and painting circuits One tube can cover up to 0.5m Use with Bare Conductive hardware
