Flux for Soldering 250 ml, No name KWS ZP-250, liquid soldering flux 250ml

No name KWS ZP-250 liquid flux in a 250 ml bottle is formulated for manual soldering and rework tasks. It improves wetting, removes oxides from metal surfaces and facilitates reliable solder flow and adhesion on copper, brass and plated surfaces. The clear liquid consistency allows controlled application to joints and pads before soldering, supporting consistent results in electronics assembly, repair and hobby work.

Advantages

This flux promotes rapid oxide removal and improved solder wetting, reducing the need for excessive heating and rework. Its liquid form enables precise application to small joints and component leads. The 250 ml volume offers a balance between portability and sufficient supply for repeated repair or assembly tasks. The formulation is suitable for common electronic metals, enabling repeatable solder joints with standard leaded and lead-free solders.

Suitable for

• Electronics assembly and PCB rework
• Repairing connectors, wires and small metal parts
• Hobby projects involving copper, brass or plated metals
• Desoldering and re-soldering component leads

Key specifications

• Form: liquid flux in 250 ml bottle
• Compatible materials: copper, brass and plated surfaces
• Application: manual soldering and rework
• Improves wetting and oxide removal for reliable solder flow

How to use

Apply a small amount of flux to the joint area or component leads prior to soldering. For PCB work, dispense the liquid flux sparingly to avoid excess residue; use a brush, syringe or dropper according to accessibility. Heat the joint with an appropriate soldering iron and introduce solder to the wetted area; the flux will promote solder flow and adhesion. After soldering, clean residues if required by the application or assembly standards using an appropriate solvent or flux cleaner.

Usage recommendations

Use with adequate ventilation and follow standard safety practices for soldering and flux handling. Avoid contact with skin and eyes; store the bottle tightly closed in a cool, dry place away from heat sources. For sensitive electronics or high-reliability assemblies, test cleaning and compatibility prior to full-scale use.
