LI-CP-03 | Carbon Paste

Likhotronics | Description:

Carbon Paste is a dispersion of carbon in an organic polymeric solution. It is specially formulated for printed electronic applications.

Likhotronics | Product Advantages:

  • One component system. ‐ No mixing required.
  • Organic system • Electrically resistive.
  • Refrigeration not required.
  • High viscosity paste – viscosity can be reduced by adding organic solvents. Solvent soluble after cure – no solubility after complete curing.

Resistivity (Ω.m) 7 x 10‐4
Adhesion 5B as per ASTM std. on PET

Likhotronics | Storage and Shelf‐life:

Containers should be stored as specified with lids tightly sealed at room temperature (25oC).

Normal shelf‐life is 6 months. Extended shelf‐life can be achieved by storing inks in a fridge at 4‐8oC (do not freeze). Allow ink to warm up to room temperature before opening.

Likhotronics | Cleaning:

The dried paste can be cleaned using solvents such as BuOAc/EtOAC.
