Kester Acid Cored Wire Technical Overview

Kester Acid Cored Wire is a highly active inorganic acid type flux wire designed for general-purpose industrial soldering, manufactured by Kester. Formulated for heavy-duty metal fabrication, this solder wire offers aggressive oxide removal and rapid wetting across a wide range of common industrial base metals.

Key Features of Kester Acid Cored Wire

Engineered for high activity and thermal endurance in demanding non-electronic assembly tasks, this product provides several technical benefits:

• Highest Flux Activity: Contains an active inorganic acid chemistry classified as INH1 under IPC J-STD-004 specifications.
• Broad Metal Compatibility: Solders virtually all common metals rapidly, with the exception of aluminum and manganese.
• Oxidized Surface Performance: Ideal for soldering excessively oxidized or tarnished metal surfaces without extensive pre-treatment.
• High Thermal Stability: Maintains flux performance under prolonged high-temperature heating, including torch and flame soldering.
• Easy Residue Removal: Post-soldering acid flux residues can be washed away easily during post-process cleaning.

Processing Guidelines & Safety Restrictions

Recommended soldering tip temperatures range from 315 to 343 °C (600 to 650 °F) for leaded alloys and 371 to 400 °C (700 to 750 °F) for lead-free alloys. Operators should preheat both the land area and lead before feeding wire directly into the joint rather than onto the iron tip to preserve tip life. If additional flux is required during rework, compatible Kester 817 liquid flux may be applied sparingly. Because of the corrosive nature of inorganic acid residues, this wire is strictly prohibited for electrical or electronic assembly.

Conclusion

In summary, Kester Acid Cored Wire offers high fluxing activity and heat stability for oxidized metals. For technical details, contact Contact – LORIOT INDUSTRIAL.
