Kapp Comet™ Flux has been designed specifically for the low temperature soldering of all common metals except Aluminum. It is an activated liquid flux, a mixture of inorganic salts in water, with approximately 35-40% active ingredients and excellent wetting properties. Kapp Comet™ Flux is highly recommended for use with KappZapp™ Silver solders on Copper and Stainless Steel. It is also excellent for use with all solders and metals except Aluminum when soldering temperature requirements are 350-550°F (177-288°C). Kapp Comet™ Flux is designed specifically to work with KappZapp3.5™ and KappZapp4™ solders to remove the oxide layer on Copper, Brass, and Stainless Steel required to form a strong bond.

Applications

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
