Use with Stay-Silv®, Safety-Silv® and other brazing filler metals. This high heat flux is designed to extend the temperature and life of the flux. This is helpful during longer part heating cycles, or in cases of intense localized heating, such as induction brazing. Extremely fluid. Will penetrate the tightest joints. Not subject to recrystallization (lumpiness-hardening). May be water thinned. Conforms to the EU Reach & RoHS directive.
