Wall Colmonoy Nicrobraz Green Stop-Off Flux, Type II | GSO-II

Nicrobraz Green Stop-Off is the strongest of all. It works with almost any type of base metal – except reactive metals, i.e. Ti, Zr. It can be used with any brazing method. It is the finest surface-protection agent and provides the best assurance for protecting a metal surface from a filler metal. Besides traditional liquid form, it also has the easiest-to-use PEN form. A little hard to remove but assures protection.
