Dimer C Parylene Conformal Coatings

Parylene C is the second most common polymer coating. Produced from the same materials as Parylene N, this dimer contains chlorine which offers excellent dielectric and physical properties.



  • Most efficacy for value
  • Faster rate of deposition than Parylene N with thicker coating in less time
  • Dielectric protection at 5k volts per 1 mil coating
  • Excellent protection from moisture, chemicals, and corrosive gases
  • Tensile strength of 10,000 psi



  • Batch processing only
  • Hardest coating to rework
  • Time required to prepare and mask boards
  • Limited UV resistance
  • Temperature limit around 120C in the presence of oxygen
  • Contains chlorine - cannot be used for medical applications
