    Code: 405402
    Barcode: 6418677405402

    Ensto SR1 – a professional, acid-free contact paste / joint gel designed to protect aluminum and other metal electrical connections. SR1 forms a thin protective layer that prevents oxidation, reduces the risk of corrosion, and helps maintain a high-quality, low-resistance contact even in humid or outdoor conditions. Due to its compatibility with plastic, metal, and concrete, as well as its safety for drinking water systems, SR1 is suitable for both household and industrial installations.

    Functions

    Oxidation prevention for aluminum – neutralizes surface oxidation, facilitates reliable contact formation.

    Corrosion protection – creates a hydrophobic (water-repellent) layer protecting the connection from environmental effects.

    Contact quality stabilization – helps maintain low transition resistance, especially under long-term loads.

    Application on wet surfaces – the gel can be applied even in moist conditions, displacing water from the contact area.

    Wide material compatibility – suitable for connections with plastic, metal, and concrete elements; safe in potable water systems.

    Applications
    Household user

    Protection of outdoor lighting, garden equipment, gate automation connections from moisture and oxidation.

    Protection of wire connections (especially aluminum) in panels or junction boxes, preventing overheating due to poor contact.

    Reducing corrosion risk in drinking water system electrical components (e.g., pump control connections).

    Engineer

    For cable connections and aluminum conductors – SR1 ensures stable electrical interaction during long-term operation.

    Suitable for test benches, prototypes, or small-scale production, where contact reproducibility and environmental control are critical.

    Useful in infrastructure and process equipment connections exposed to moisture and temperature fluctuations.

    Electrician

    For cable joints and lugs – especially aluminum conductors, compatible with Ensto series SLxx, SMxx, KGxx.

    For terminals, screw connections, and equipotential bonding points in panels and junction boxes.

    For outdoor and industrial installations – where condensation, rain, salty or dusty environments are common.

    Pros

    Acid-free formula – does not cause additional corrosion.

    Works on wet surfaces, suitable for outdoor use.

    Compatible with potable water – wide application in building engineering.

    Wide temp. range (–30…+110 °C) – stable results all year round.

    Convenient tube packaging (225 ml) – economical and clean dispensing.

    ETIM classification – easy to identify and specify in projects.

    Cons

    Does not solve problems of poor mechanical connection or improper tightening.

    Gel may attract dust; neat application and removal of excess are important.
