Kapp Comet Liquid Flux

Best used in applications suited for KappZapp3.5™ and KappZapp4™ solders such as:

• Sensitive electronic parts
• Circuit boards
• Thin wires
• Instruments
• Copper wires to Copper, Brass, and/or Stainless Steel tabs
• Effective fluxing action on metal surfaces is 350-550°F (177-288°C)
• NOTE: COMET FLUX WILL CHAR AT TEMPERATURES EXCEEDING 550°F (288°C)
• Choose CopperBond™ Flux for higher soldering temperatures on Non-Aluminum Metals
• IMPORTANT: Overheating Kapp Comet™ Flux will be detrimental to your soldering project. Kapp Comet™ Flux will char above 550°F (288°C) requiring you to stop, let the joint cool, clean the joint, and re-solder to ensure a proper bond.
• Residue is slightly corrosive, and easily removed with hot water rinse, or a clean wet rag 

Many factors, such as materials, temperature, and method of application determine the most effective flux. Call Kapp for engineering assistance to discuss your specific needs. We recommend testing appropriate fluxes in your specific application to ensure suitability.
