Adhetron EL-Tech 152 Silver-Filled Conductive Coating Paste

Adhetron EL-Tech 152 Silver-Filled Conductive Coating Paste is a technical material intended to form an electrically conductive coating with its silver-filled, single-component structure. Its applicability via screen printing (silk screen), dipping, or syringe dispensing makes it easier to create a controlled film in both prototyping and production environments. The formulation is designed to target good adhesion on substrates such as flexible plastics and glass, while maintaining the coating’s flexibility. The manufacturer brand Adhetron is a portfolio brand offered under Pulsar Kimya.

Definition and structure of EL-Tech 152 conductive coating paste

EL-Tech 152 is defined as a silver-filled, single-component system that forms an electrically conductive, flexible coating. Its “paste” character helps manage flow behavior in applications where thin and controlled coating traces must be formed. The product is positioned to adhere not only to flexible plastic films (Kapton, Mylar, polyimide) but also to harder surfaces such as glass. The coating approach focuses on forming a film that is flexible, chemically resistant, expandable, and abrasion-resistant. This definition offers a technical advantage for moving or flexible surface scenarios where the coating is expected to function without cracking after application.

Application methods and curing conditions

Application can be carried out using one of the methods described by the manufacturer: screen printing, dipping, or localized syringe dispensing. Preparing the substrate to be clean, dry, and suitable for the process is critical for film thickness and electrical continuity, so preliminary trials are recommended in production. Curing is managed through a thermal cure profile, with different time options at different temperatures. According to the document, fast-cure alternatives include 30 minutes at 50°C, 10 minutes at 80°C, 5 minutes at 100°C, 3 minutes at 125°C, or 1 minute at 150°C. The thermal profile should be selected by considering both the targeted cycle time and the thermal resistance of the substrate being coated.

Electrical performance and durability profile

The primary factor enabling conductivity in the coating is the silver filler, and the silver content is stated as greater than 84%. Electrically, a maximum volume resistivity value of 0.00003 Ω·cm is provided; this is one of the key reference parameters in conductive film design. For thin-film applications, sheet resistivity is listed as 0.010 Ω/square at a 25 µm film thickness. Since the temperature resistance is stated as -50 to +200°C, suitability for electrical/electronic applications exposed to thermal cycling can be assessed within this range. In terms of mechanical properties, the product is described as a flexible, deformation-resistant, and abrasion-resistant coating, and the emphasis on chemical resistance becomes important in scenarios where contact with process chemicals is possible. With viscosity given at approximately 10,000 cPs, equipment and mesh/nozzle selection in printing/dispensing processes should be planned according to this consistency.

Storage, shelf life, and process notes

Shelf life is specified for sealed containers depending on storage temperature: 6 months at 25°C, 9 months at 5°C, and 12 months at -10°C. Therefore, especially in production planning, cold storage and shelf-life management should be considered together. Since the manufacturer recommends trial work to verify application-specific requirements, sample coating and measurement steps should be part of the process before mass production. For safety documentation (MSDS/SDS), the manufacturer indicates a request-by-email method; for companies with EHS processes, planning to obtain this document during procurement is appropriate.

Use cases and compatible substrates

This conductive coating paste is positioned for applications in electrical/electronics production processes where a conductive film or conductive coating is needed. The goal of good adhesion on flexible plastic films (Kapton, Mylar, polyimide) supports its use in manufacturing steps that require coating on flexible circuit carriers and film-based substrates. The emphasis on adhesion to rigid surfaces such as glass indicates it can also be evaluated for processes where a conductive layer must be formed on glass in certain subsystems. Being applicable via screen printing supports a repeatable patterned trace/coating approach in mass production, while syringe dispensing accommodates localized touch-ups and spot-coating needs. The stated chemical resistance and abrasion resistance can contribute to performance continuity where post-process cleaning steps or mechanical contact risks exist. Since the product focuses more on the “conductive coating” function than on bonding, the target use scenario is to obtain a film on the surface that provides electrical continuity while retaining flexibility.
