Ultra Flux Silver Solder Flux 1 lb. Jar

Ultra Flux is a water-based paste consisting of a unique combination of potassium salts of fluorine and boric acid. Ultra Flux can be used in the concentrated form or can be diluted.

Ultra Flux can be applied using a brush, dip or spray. The wetting ability is excellent. Vertical adherence as applied and upon heating is excellent. There is no spatter when heating with concentrated flux, slight spatter will occur with water diluted flux due to escaping steam. Ultra Flux has excellent adhesion without cracking when applied to parts which are air dried or heat dried before brazing. It also has a long storage life without crystallizing or caking.

Protection of parts and flux life under heating are excellent. Oxide absorption and brazing alloy flow are also excellent on all metals when Ultra Flux is used.
