KC Solder Flux

KC 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. KC Flux is highly recommended for use with KZR35 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). KC Flux is designed specifically to work with KZ35R and KF solders to remove the oxide layer on Copper, Brass, and Stainless Steel required to form a strong solder bond.

 Applications:

• Best used in applications suited for KZ35R solder 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: KC FLUX WILL CHAR AT TEMPERATURES EXCEEDING 550°F (288°C)
• IMPORTANT: Overheating KC Flux will be detrimental to your soldering project. KC 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
