Soldering Flux Liquid AG TermoPasty SOLD-ACID/100 100 ml – acid flux for soldering

AG TermoPasty SOLD-ACID/100 is a 100 ml liquid acid flux formulated to promote wetting and remove oxides from metal surfaces prior to soldering. Designed for manual and small-scale electronic and general metalwork applications, this liquid flux helps prepare joints and improve solder flow to achieve reliable metallurgical bonds where an active, acid-based flux is required. The product is supplied in a compact 100 ml container for controlled application; appropriate personal protective equipment and ventilation should be used during handling.

Advantages

This acid flux improves solderability by effectively cleaning oxide layers and enhancing solder flow into joint clearances. In liquid form it allows precise application on small areas, speeds up wetting, and reduces the need for extensive mechanical cleaning. The formulation is intended for use where an active flux action is necessary to achieve dependable joints on mildly oxidised or corroded metal surfaces.

Suitable for

• Manual soldering of electronic components on metal leads and terminals
• Small-scale metal repairs and joining of copper, brass and similar alloys
• Maintenance tasks requiring active acid flux to restore wetting on oxidised surfaces
• Hobby and workshop projects that demand targeted application of flux

Key specifications

• Form: liquid flux
• Volume: 100 ml
• Flux activity: acid (active)
• Application method: brush, dropper or syringe for precise dosing
• Intended use: manual and small-scale soldering of electronic and metal parts

How to use

Apply a small amount of flux to the cleaned joint area using the container nozzle, brush or a fine applicator. Proceed with soldering once the flux has been applied, allowing the solder to flow and form the metallurgical bond. After soldering, remove any residual flux according to the safety and cleaning guidance: some acid flux residues can be corrosive and should be cleaned off using appropriate solvents or water and drying, depending on the substrate and flux instructions. Always work in a well-ventilated area and wear appropriate gloves and eye protection.

Usage recommendations

Use this acid flux only on compatible metals and for tasks that require active flux action. Avoid use on sensitive electronic assemblies unless subsequent cleaning is planned. Store the product in a cool, dry place away from children and foodstuffs. Dispose of residues and empty containers according to local regulations.
