From the outset of its design, the purpose of Green Stop Off was to ensure it had broad adaptability. It can be used in the brazing processes of almost all parent metals (except for metals that react with it, such as titanium and zirconium). There are no specific requirements for the type of brazing, as it can be applied in the brazing processes of various filler metals. It is currently the best brazing stop-off material, providing technical support to protect metal surfaces where the brazing filler cannot reach during the brazing process, thereby providing optimal brazing protection. By restricting the brazing filler to only remain in the brazing gaps, it can effectively reduce the amount of filler used. Apart from this, its main function is to protect areas that don't need to be brazed during the brazing process. When using flame spraying of metal coatings, it's often used to shield related areas from being covered.
