Signis range of inks

Our CNT-based inks have been engineered to satisfy not only the requirements of specific advanced materials applications, but also to be adaptable to a variety of manufacturing technologies, including screen printing, spray coating and roll-to-roll manufacturing.

 

  • VC 102

    VC102

    Screen Printable Transparent Conductive Ink

    Specially formulated from CHASM’s patented V2V™ ink vehicle and industry-leading single-wall CNTs, VC102 delivers printable, flexible transparent conductors with superior environmental robustness and optical performance than commercial alternatives such as PEDOT.  VC102 is well-suited for cost-effective transparent circuit production at high volumes for touch buttons and sensors used in many applications including appliances, automotive interiors, and industrial controls.  Developed in direct response to repeated feedback from printed electronics manufacturers, VC102 balances value, printing consistency, simplicity of patterning and environmental stability.  VC102 is well suited to high volume transparent FPC applications.  Suitable for harsh environment applications, VC102 successfully completed 1,000 hours of environmental testing at 65°C / 85% RH, exhibited minimal variation in resistance while transparency, haze and color remained very stable. 

    PRODUCT BENEFITS

    • Typical optoelectronic values: 800 – 1,000 ohm/sq at 85% VLT
    • A neutral colour – does not impart clue colour cast to transparent circuits
    • Low-temperature drying (110°C)

    • Screen printable on a variety of flexible substrates
    • Low processing cost (< 3 min residence time)
    • Excellent adhesion to various substrates

    • Solvent based, containing no surfactants
  • VC 101

    VC101

    Tunable Transparent Conductive Ink

    Designed to serve a range of transparent conductors where tuning sheet resistance is desired. VC101 is a carbon nanotube ink designed for screen printing transparent conductors on a wide range of plastic films. VC101 can be tuned to desired specifications by printing in successive layers without the need for rinsing operations or high-temperature baking to remove surfactants, dispersing agents and rheology modifiers.  

    • Tunable by printing successive layers; 1,000 – 4,000 ohm/sq
    • 3,700 Ohm/sq at 93% VLT
    • Conductive CNTs produced using CoMoCAT™ technology

    • Polymer binder to promote adhesion

    • Solvent-based ink vehicle made using V2V™ viscous-to-vapour technology developed by Chasm Technologies (patents pending).
