Designed to protect metal surfaces from the flow of molten brazing filler metal or to prevent metal surfaces from adhering to each other during furnace brazing, Wall Colmonoy’s Stop-Off products are available in two grades: fast drying Type I (lacquer based), and nonflammable Type II (water based).
Often we are asked which Nicrobraz® Stop-Off™ product best fits their application, so we created a Nicrobraz News Issue to provide some tips on selecting Stop-Off.
Our Nicrobraz® Stop-Off™ products do not have a shelf life as these materials are not known to breakdown or deteriorate, when properly stored in an unopened container.
