Soldering Flux Gel UNIPAK UNIŻEL C-39 125 g by UNIPAK

UNIPAK UNIŻEL C-39 soldering flux gel in a 125 g container is formulated to assist soldering operations by improving wetting, heat transfer and solder flow. The gel consistency enables controlled, local application on electronic components, circuit boards and small metal parts, reducing surface oxidation during heating and helping achieve reliable joints with common solder alloys. The product is intended for repair, assembly and precise rework tasks where minimal spreading and targeted fluxing are required.

Advantages

The gel texture ensures accurate placement and minimal run-off compared with liquid fluxes, while promoting consistent solder flow and wetting of surfaces. It reduces oxidation at the joint area during heating, which helps form cleaner solder connections. Packaged in a 125 g container, the flux provides enough volume for repeated small-scale repairs and assembly jobs, and its formulation is compatible with standard solder alloys used in electronics and light metal work.

Suitable for

• Soldering and rework on printed circuit boards and electronic components
• Local soldering of small metal parts and connectors
• Repair and assembly tasks requiring precise flux application
• Hobbyist and professional electronics maintenance where controlled flux placement is needed

Key specifications

• Form: gel for controlled application
• Net weight: 125 g container
• Function: improves wetting, solder flow and heat transfer during soldering
• Compatibility: designed for use with common tin-based solder alloys
• Application area: electronics and small metal joining tasks

How to use

Apply a small amount of UNIPAK UNIŻEL C-39 flux gel directly to the joint area before heating. For electronic work, place flux precisely on pads, component leads or connector surfaces; avoid excessive application. Heat the joint with an appropriate soldering iron or station until solder flows and wets the surfaces. After soldering, allow the assembly to cool and, if required for the application or cleanliness standards, clean residual flux according to recommended procedures using suitable solvents or flux removers. Follow standard safety precautions such as adequate ventilation and appropriate personal protective equipment.

Usage recommendations

Use minimal flux to achieve the joint to reduce cleaning effort. When working on sensitive electronics, test compatibility of the flux with circuit materials and clean residues if necessary. Store the container tightly closed in a cool, dry place to maintain gel consistency.
