Product Description

DM-CAP-4103S (1000Ω/sqr/25µm) is a single part screen printable thermoset carbon paste that is resistant to solvents such as MEK (Methyl Ethyl Ketone) and offers exceptional levels of hardness (9H). Typical applications include; EMI/RFI shielding of flexible substrates, polymer thick film circuitry, potentiometers, membrane switches and printed resistors.

Product Benefits

  • Excellent hardness (9H)
  • Excellent resistance to solvents including MEK (Methyl Ethyl Ketone)
  • Excellent conductivity (<1000 Ω/sqr/25µm at 200oC cure)
  • Single part system with excellent printability
  • Paste systems at variable sheet resistance available: <10, 100 and 10,000 Ω/sqr/25µm

Paste Preparation

The paste is a single part system. Gently stir before use. Avoid rapid stirring to prevent air entrapment during the stirring process. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the original container.
