    What Is Fernox Powerflow Paste?

    Fernox Powerflow Paste is a traditional, water-soluble flux used during soft soldering. It prepares metal surfaces by removing surface oxides and preventing further oxidation while heat is applied. Consequently, solder flows smoothly and bonds effectively.

    Unlike low-quality fluxes, Powerflow Paste delivers consistent performance without excessive residue. Therefore, joints remain clean and professional once installation is complete.


    Key Features of Fernox Powerflow Paste

    Fernox Powerflow Paste offers several practical features that support efficient installation work. It activates quickly when heated, which speeds up the soldering process. At the same time, it maintains control, reducing the risk of weak joints.

    Because the paste spreads easily, installers can apply it accurately without waste. In addition, its water-soluble formulation allows for simple post-installation cleaning.


    How Fernox Powerflow Paste Works

    When applied to cleaned copper surfaces, Fernox Powerflow Paste removes remaining oxides. During heating, it shields the metal from further oxidation. As a result, solder bonds evenly across the joint.

    Once soldering is complete, any remaining flux residue dissolves easily in water. Therefore, systems stay clean and corrosion risks remain low.


    Applications and Suitable Uses

    Plumbing Installations

    Fernox Powerflow Paste suits hot and cold water plumbing systems. It supports reliable solder joints on copper pipes, elbows, tees, and fittings. Therefore, installers can work confidently on domestic plumbing projects.

    Heating and Renewable Systems

    The paste also works well in central heating pipework. It supports installations involving boilers, radiators, and renewable heating components. As a result, engineers maintain high standards across traditional and modern systems.
