Adhetron EL-Tech 142 Silver-Filled Conductive Coating Paste

Adhetron EL-Tech 142 is a silver-filled, electrically conductive coating paste that can be cured at low temperatures. Thanks to its single-component form, it can be used in production without mixing and is designed to form a flexible conductive layer as a film. It stands out particularly in applications such as creating conductive traces and improving electrical contact on substrates where soldering is not possible or where heat sensitivity is a concern. The Adhetron brand operates under Pulsar Kimya Sanayi ve Ticaret A.Ş. (Pulsar Chem. Industry and Trade Co. Inc.), based in Türkiye.

Product description and composition of the EL-Tech 142 conductive coating paste

EL-Tech 142 is a standard-grade, paste-like electrically conductive coating product with a high silver filler content. From a chemical perspective, it can be considered a composite coating in which metallic silver filler—responsible for conductivity—is dispersed within a polymeric binder system. After curing, it forms a flexible film layer with enhanced chemical resistance and helps achieve a surface that is more resistant to abrasion. This structure provides a practical solution for production lines that require conductivity on both flexible and rigid substrates.

Technical performance, durability, and substrate compatibility

The product is positioned to deliver high adhesion performance on flexible plastics such as Kapton, Mylar, and polyimide, and it can also be applied to rigid surfaces like glass. Once cured, the coating exhibits a chemically resistant and deformation-resistant character, aiming for more stable conductivity at contact points. In technical data, the operating temperature range is given as -55 °C to +200 °C, offering a broad working window for electronics and industrial applications. In terms of electrical performance, the volume resistivity is specified at 0.00004 Ω·cm, supporting the formation of a low-resistance conductive layer in thin-film applications.

Curing and electrical properties

EL-Tech 142 is suitable for fast curing via low-temperature oven baking; typical cure schedules are specified as 30 minutes at 50 °C, 10 minutes at 80 °C, 5 minutes at 100 °C, 3 minutes at 125 °C, and 1 minute at 150 °C. This approach helps manage the process more reliably in assemblies that include heat-sensitive components. The sheet resistivity is specified as 0.015 Ω/square at a 25 µm film thickness, which can be used to validate design targets in applications such as conductive traces and shielding. In terms of storage, the shelf life in a closed container is stated as 6 months at 25 °C, 9 months at 5 °C, and 12 months at -10 °C.

Application method and process recommendations

Application can be carried out by screen printing, dipping, or syringe dispensing, making it suitable for both high-volume production and localized repair/conductive trace completion work. For best results, surfaces should be cleaned of oil, dirt, and oxide residues; if necessary, an appropriate surface preparation step is recommended to improve wetting. Coating thickness should be controlled within the process according to the targeted resistance values, since conductivity performance can vary as film thickness increases—making sample trials critical. Safety documentation (SDS/MSDS) should be obtained from the manufacturer upon request, and site procedures should be updated accordingly.

Industry applications and key advantages

In electronics manufacturing, it is suitable for applications such as forming conductive traces, refurbishing contacts, and completing interconnections on flexible circuit carriers that cannot be soldered. In sectors such as defense and aerospace, low-temperature curing can help reduce production constraints in circuits that include heat-sensitive components. In industrial maintenance and prototyping processes, it can be considered for creating conductive tracks on glass or engineering plastics, and for improving surface contact in shielding and grounding connections. Its single-component, paste-like form offers operational advantages such as easy dispensing, repeatable application, and compatibility with different substrate types.
