Applying the boron nitride coating of the type Solder-Stop BN10 covers areas of the substrate to be protected efficiently and prevents during the brazing the unwanted running of the solder. Solder-Stop BN10 is applied to the areas to be protected by brushing or spraying. It can be used at air to 1000°C and is compatible with mist materials used with brazing such as copper solder, silver solder or AlSi-solder. Solder-Stop BN10 is suitable with the brazing of iron, copper and nickel material as well as aluminium. As a concentrate for highest requirements the product Solder-Stop BN25 is available. Alternatively the quick drying product Boron-Nitride-Coating Grade E can be used.
