Carbon Ink (C-250J)

Low-Resistance Carbon Screen Printing Ink Ideal for screen printing membrane switches and flexible circuits Product Information | Process Recommendation | MSDS | Related Products | Technical Support A carbon-graphite conductive ink engineered for screen printing applications. The low-resistance paste makes it ideal for printing membrane switches and flexible electronics. This carbon ink delivers superior mechanical durability for excellent resistance against wear from surface-mounting technology components and hybrid circuits, alongside exceptional adhesion (5B, ASTM D3359) to pre-treated PET and common rigid PCB substrates. Screen Printing Carbon Ink Highly conductive and strong adhesive coating Versatile Applications Flexible printed circuits and membrane switches High Quality Formulation For reliable and impactful electronics research Low Resistance Material Tailored conductivity with mechanical durability Product Information Product Name Heraeus Electronics, PriElex™ C-250J CAS Number 1333-86-4/7782-42-5 Chemical Formula C Other Names Carbon conductive ink, conductive carbon ink, carbon screen printing ink, carbon paste Classification or Family Screen printing, Flexible electronics, Carbon, Conductive inks Solid Content 50 ± 2% Solvent Diethylene glycol monoethyl ether acetate (DEGMEA), naphtha Particle Size < 25 µm (D95) Resistivity ≤ 0.022 Ω⋅m Viscosity 23.5 – 36.5 kcPs (Vt-04, No.2 spindle, 25 °C) Theoretical Coverage 160 m2/kg (14 µm thickness) Appearance Black ink/paste Product Gallery Previous Next Process Recommendation Use Mix thoroughly before use Type of Screen Polyester Mesh (157 to 230 TPI) or steel Mesh (165 to 325 TPI) Recommended Substrates Print-treated PET, rigid PCB substrates Drying Temperature 100 – 130 °C Cleaning Suitable screen cleaner with a final pass of acetone/MEK to clean up any residual solvents/film MSDS Documentation C-250J Carbon Ink MSDS Sheet Related Products [[collection handle="screen-printing-conductive-inks" limit="5"]] Screen Printing Conductive Inks Screen Printing Conductive Inks Thin Film Coating Equipment Thin Film Coating Equipment Popular Materials Popular and New Materials
