Silver conductive ink is basically a liquid form of metal that you can draw or dispense anywhere you need electricity to flow. Microscopic silver particles suspended in a binder turn into an unbroken metallic path as the liquid dries, giving you near-bulk-silver conductivity without soldering, copper foil, or heavy printing equipment. Because the trace cures at mild temperatures, resists corrosion, and works on paper, plastic, fabric, or glass, the same chemistry powers quick PCB repairs, biomedical electrodes, flexible heaters, and our own Electricity on Pape kit, where kids or hobbyist sketch LED circuits right on paper using silver conducting ink pen.
How silver conductive ink works
Silver ink contains nano- to micro-scale silver particles suspended in a resin and solvent. When the solvent evaporates, the particles sinter at mild temperatures—sometimes even at room temperature depending on the formulation. The resulting track shows resistivity as low as 1 – 10 µΩ · cm, only a few percent above pure silver. Silver’s surface tarnish (mainly silver-sulfide) remains electrically conductive, so the line keeps its low resistance even in humid air.
Key Advantages
- Ultra-low resistance – A silver trace carries current about 5 % better than an equal-width copper trace, so designers can shrink line widths or cut voltage-drop in high-current paths.
- Mild, air curing – Ink cures even at room temperature. Safe for use on paper, PET film, and fabric without damage.
- Oxidation resistance – Copper oxide is an insulator, whereas silver’s thin tarnish continues to conduct, keeping circuits reliable for years without encapsulation.
- Surface versatility – Formulations adhere to plastics, glass and fabric.
- Viscosity – Less than 1 Pa·s, allowing smooth application with brush or blade.
Everyday Uses
- Rapid PCB trace repair
- EMI Shielding
- Prototyping
How to Use It
- Shake well to remix silver particles.
- Draw or dispense a smooth line where you need conductivity.
- Let it Dry completely.
- Test with a multimeter good lines show only a few ohms or less.
- Store sealed below 27 °C for maximum shelf life.
