Electroninks launches UV-curable silver ink for printed electronics and EMI shielding

Electroninks on June 15 launched EI-1169, a UV-curable silver conductive ink for inkjet printing across advanced electronics manufacturing. The Austin company says the new material is built for lower-temperature processing, strong adhesion and EMI shielding use cases. Why it matters: - EI-1169 gives electronics makers a new silver conductive ink designed for additive manufacturing, printed electronics and EMI shielding. - The product is aimed at temperature-sensitive substrates and advanced packaging workflows where low-temperature curing and stable jetting matter. - Electroninks is expanding a portfolio built around metal-organic decomposition conductive inks for semiconductor packaging and other advanced applications. What happened: - Electroninks announced EI-1169, a UV-curable silver conductive ink for inkjet deposition. - The launch was made on June 15, 2026, from Austin, Texas. - EI-1169 is designed for high-reliability conductive printing on epoxy, polyimide and copper substrates. - The company says the product is available immediately for customer evaluation and integration. - More information is available on Electroninks’ website . The details: - EI-1169 is a polymer-free MOD silver conductive ink. - The formulation is lead-free and halogen-free. - The ink supports UV curing at 365 nm or 395 nm wavelengths. - Electroninks says the material offers stable jetting performance on industry-relevant printheads. - The ink also has long refrigerated shelf stability and strong adhesion on copper, epoxy and polyimide substrates. - The company says EI-1169 shows strong stability and ink-jettability in several printheads, including DMP Samba printheads. - Electroninks says the combination is meant to support scalable additive manufacturing workflows and consistent production output. - The product is positioned for printed electronics, flexible electronics, semiconductor packaging, advanced interconnects and additive manufacturing workflows. Between the lines: - The launch reflects a broader push toward digitally manufactured electronics, where manufacturers want more precise deposition and less thermal stress. - Electroninks is signaling that process reliability is as important as conductivity in the market for advanced conductive materials. - The company is also broadening beyond silver into copper, gold, platinum and nickel chemistries, which suggests a larger materials platform strategy. What’s next: - Electroninks expects customers to test EI-1169 in EMI shielding, printed electronics, semiconductor packaging and related workflows. - The company will likely use the new ink to deepen its presence in additive electronics manufacturing and advanced packaging. - Electroninks says it continues developing conductive ink solutions for printed circuit boards, advanced sensors, aerospace systems and medical devices. The bottom line: - EI-1169 is a targeted product launch built to make conductive printing easier on more substrates, at lower temperatures and with more process flexibility.
