Soldering Paste / Flux for Soft Soldering 100 g, No name PASTA D100

Soft soldering paste (flux) in a 100 g container designed to improve wetting and facilitate joining of copper, brass and other common metals during low-temperature soft soldering. This flux is formulated for manual soldering and repair tasks, helping to remove surface oxides and promote consistent flow of solder to form reliable joints in electronics hobby projects, small plumbing repairs and general metalwork where a low-temperature solder is used.

Advantages

The soldering paste provides improved solder wetting and reduces the need for mechanical cleaning of metal surfaces prior to joining. Its paste consistency allows controlled application to small joints and vertical surfaces without immediate run-off. The formulation supports cleaner joints with fewer voids and assists in achieving good electrical and mechanical contacts in delicate assemblies and repair work.

Suitable for

• Hand soldering of copper and brass components
• Electronics hobby projects and circuit repairs
• Small plumbing and fitting jobs requiring soft solder
• General metalwork and light repair tasks

Key specifications

• Form: paste (thick flux) in a 100 g container
• Application temperature: suitable for low-temperature soft soldering processes
• Compatibility: designed for common base metals such as copper and brass
• Application method: manual application with brush, spatula or applicator

How to use

Clean visible dirt and major oxidation from the surfaces to be joined before applying a small amount of paste to the joint area. Apply soldering paste sparingly to avoid excess residue; use a brush or spatula to spread the paste evenly. Heat the joint with a soldering iron or torch appropriate for soft soldering until the flux activates and the solder flows to form the joint. After soldering, allow the assembly to cool and, where necessary, remove flux residues according to the cleaning guidance for the specific flux type to prevent long-term corrosion or conductivity issues.

Usage recommendations

Use appropriate personal protective equipment, adequate ventilation and follow standard safety practices for soldering. Avoid applying flux to electronics without verifying post-solder cleaning requirements for the specific assembly. Store the container tightly closed in a cool, dry place and keep out of reach of children.
