Rosin Flux Paste AG TermoPasty AGT-034 active soldering flux paste, 40 g

AG TermoPasty AGT-034 active rosin flux paste is a 40 g container of flux formulated to improve wetting and remove oxides during soldering. Intended for manual and reflow soldering processes, this rosin-based paste assists with consistent solder flow and formation of reliable joints on electronic components, PCB traces and general electrical connections. The product provides a controlled application for small repair jobs and production tasks where a compact, easy-to-handle flux is required.

Advantages

The rosin flux formulation promotes improved wetting and reduces soldering defects by cleaning oxides and contaminants at the joint area. Supplied as a paste in a 40 g container, it enables precise, repeatable application on small surfaces and component leads. Compatibility with both hand soldering and reflow processes makes the paste versatile for repair and manufacturing environments. The consistency of the paste supports uniform solder flow and helps achieve reproducible solder joints.

Suitable for

• Soldering and repairing printed circuit boards (SMT and through-hole)
• Manual soldering of component leads, connectors and wires
• Reflow soldering processes for small batches or touch-up work
• Electrical connections and general electronic assembly maintenance

Key specifications

• Form: rosin-based flux paste
• Activity: active flux suitable for oxide removal
• Package weight: 40 g container
• Application methods: manual dispensing, syringe or brush application for precision
• Compatibility: suitable for hand soldering and reflow soldering processes

How to use

Apply a small amount of paste to the soldering area using a suitable applicator such as a brush, spatula or syringe tip to ensure targeted coverage. Preheat the board or component as required by the soldering procedure, then apply solder with the iron or reflow process while allowing the flux to activate and remove oxides. After soldering, remove residues according to the cleaning practice appropriate for the assembly and flux type if necessary; follow workplace safety and handling instructions when working with active fluxes.

Usage recommendations

Store the container tightly closed in a cool, dry place away from direct sunlight. Use small amounts to avoid excessive residue and follow manufacturer guidance for post-solder cleaning if a cleaner flux residue is required for the application. Wear appropriate personal protective equipment and ensure adequate ventilation during soldering.
