Kapp Lunar Flux™
 

KAPP Lunar flux is a white paste for high temperature soldering of aluminum and zinc die cast alloy. It is a reaction-type flux with 70% active ingredients dispersed in alcohol. It demonstrates considerable shelf life stability, as the suspending agents prevent separation and recrystallization 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 Lunar Flux in production processes are available from Kapp Engineering Assistance. Please call for further assistance.

Recommended soldering alloys: Alumite and all compositions 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.

CAUTION: WHEN USED WITH ALUMINUM, TOXIC FUMES WILL BE GIVEN OFF. CALL KAPP ENGINEERING ASSISTANCE FOR FURTHER INFORMATION. READ AND UNDERSTAND THE MATERIAL SAFETY DATA SHEET.
