LI‐CP‐04 | Carbon Paint
Likhotronics | Description:
Carbon paint is a resistive carbon material in an organic polymeric solution. It is specially formulated to create electronic application on paper on a bigger canvas. It can be applied on paper through brush and create a large area circuit.
Likhotronics | Product Advantages:
- One component system. ‐ No mixing required.
- Solvent based system
- Electrically resistive
- Refrigeration not required.
- Low viscosity paste – viscosity can be further reduced by adding solvent.
Likhotronics | Ink Preparation:
Stir (or shake) the ink thoroughly before use to ensure the product is well mixed, care should be taken to avoid introducing air bubbles. Do not add used ink back into the container to avoid cross contamination.
Likhotronics | Possible application:
To make a circuit on bigger canvas. DIY application. Capacitive sensor
Likhotronics | Properties of the Uncured Paste:
