Kapp Lunar Flux™ - Soldering Flux for Aluminum550°F- 800°F (288°C - 427°C)
Kapp Lunar Flux™ is a white paste for the high temperature soldering of Aluminum and Zinc die cast alloy. It is a reaction-type flux with 70% active ingredients dispersed in alcohol. 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 die cast surfaces is also consistent over time.
Benefits and Uses
Kapp Lunar Flux™ works well on all common Aluminum and Zinc die cast alloys. Specific guidelines for using Kapp Lunar Flux™ in production processes are available. Please call Kapp Alloy & Wire for further assistance.
Recommended soldering alloys: Alumite™ and KappAloy30™ or higher Zinc content Tin-Zinc alloys, 50% Tin - 50% Lead; or any alloy/application for Aluminum soldering which demands working temperature range between 550°F and 800°F (288°C - 427°C).
CAUTION: WHEN USED WITH ALUMINUM, TOXIC FUMES WILL BE GIVEN OFF. PLEASE READ AND UNDERSTAND THE MATERIAL SAFETY DATA SHEET.
The following chart represents the physical properties of Kapp Lunar Flux™. 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. Samples of Kapp fluxes are always available upon request.
