Product Description

DM-CAP-4101S is a single part screen printable thermoset carbon paste that is resistant to solvents such as MEK (Methyl Ethyl Ketone). It offers exceptional levels of hardness(5H) and electrical conductivity(<50Ω/sqr/25µm). Typical applications include; EMI/RFI shielding of flexible substrates, polymer thick film circuitry, potentiometers, membrane switches and printed resistors.

Product Benefits

• Excellent hardness (2H)
• Excellent resistance to solvents including MEK (Methyl Ethyl Ketone)
• Excellent conductivity (<50 Ω/sqr/25µm at 200oC cure)
• Single part system with excellent printability
• Paste systems at variable sheet resistance available: 100, 1000 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 put used paste back into the original container.
