Kapp Lunar™ Flux is a white paste for the high temperature soldering of Aluminum and Zinc Diecast alloys. It is a reaction-type flux with 70% active ingredients dispersed in alcohol. The paste stays where it is applied to simplify the soldering process. Kapp Lunar™ Flux has considerable shelf life stability, as the suspending agents prevent separation and re-crystallization of the active ingredients. The performance of the paste in depositing Zinc on Aluminum and Diecast surfaces is also consistent over time.

Applications

  • Higher temperature soldering of Aluminum and Zinc Diecast parts such as:
  • Automobile hardware
  • Marine parts such as propellers
  • Works well on all common Aluminum and Zinc Diecast alloys
  • Recommended soldering alloys:
  • Any alloy/application for Aluminum soldering which demands working temperature range of 550-800°F (288-427°C).
  • CAUTION: WHEN USED WITH ALUMINUM, TOXIC FUMES WILL BE GIVEN OFF. PLEASE READ AND UNDERSTAND THE PRECAUTIONS AND PROCEDURES ON THE SAFETY DATA SHEET .
