⚡ ARMACK AMASAN ZWN soldering flux 250 g

ARMACK AMASAN ZWN 250 g is a professional liquid flux, known as soldering water, intended for soft soldering components made of galvanised steel sheet, technically pure zinc and titanium zinc.

The product complies with classification DIN EN 29454-1 3.2.2A (F-SW 11). It effectively prepares surfaces before soldering by dissolving oxide layers that hinder proper wetting of the material by the solder.

An important advantage of ZWN flux is that it does not leave stains or damage the zinc surface. This allows the material to retain its protective properties and resistance to corrosion.

✅ Key benefits of ARMACK ZWN flux

• Intended for soft soldering zinc and galvanised sheet.
• Effectively dissolves oxides on the surface of soldered components.
• Leaves no stains on the zinc surface.
• Does not damage the zinc coating when used correctly.
• Helps maintain zinc’s corrosion resistance.
• Liquid consistency makes it easier to apply the product precisely to the joint area.
• Suitable for galvanised steel sheet, pure zinc and titanium zinc.
• Suitable for roofing, sheet-metal work and workshop applications.
• 250 g pack – practical for regular soldering work.

✅ Effective oxide removal

During soldering, the zinc surface may be covered with an oxide layer that makes the solder flow correctly more difficult. ARMACK ZWN effectively dissolves oxides, preparing the surface for making the soldered joint.

This allows the solder to wet the prepared surface more effectively, making it easier to create even and durable joints during soft soldering.

✅ Without damaging the zinc surface

One of the most important properties of ZWN flux is its action adapted to zinc surfaces. The product does not cause staining or damage the zinc, allowing the surface to retain its anti-corrosion properties after the joint has been made.

This is particularly important during roofing and sheet-metal work, where both joint quality and preservation of the processed material’s protective properties are important.

✅ Application

ARMACK AMASAN ZWN is intended for the soft soldering of:

• galvanised steel sheet,
• technically pure zinc,
• titanium zinc.

The product is used, among other applications, for:

• roofing work,
• soldering sheet-metal flashings,
• joining zinc-sheet components,
• soldering titanium-zinc components,
• repair and renovation work,
• professional workshop work.

✅ For use with soft solders

ARMACK states that ZWN flux can be used, among other applications, with the following solders:

• ARMACK S-Sn60Pb40 (LC60),
• ARMACK S-Sn50Pb50 (LC50).

The choice of solder should depend on the type of material being soldered, the intended use of the joint and the technical requirements of the particular application.

✅ Instructions for use

Before soldering, the surface must be properly cleaned of loose dirt, grease and other contaminants. Apply ZWN directly to the joint area, preferably using a suitable brush for soldering products.

Next, heat the joint area and apply a suitably selected soft solder in accordance with the technical requirements.
