BrazeLet® Stop-off products
– to perfect your brazing applications
A stop-off brazing solution that prevents flow of molten brazing filler metals
BrazeLet® Stop-off is an effective product when you would like to prevent flow of molten brazing filler metal into areas where it is not wanted or needed. The BrazeLet Stop-off product family includes three different products, for either general stop-off brazing use or optimized for easier removal after brazing when a shiny surface is preferred.
These stop-off brazing solutions act as a barrier to the flow of molten brazing filler metal and consist of ready-to-use water-based suspensions designed for general use. They work very well in high-temperature brazing together with any of Höganäs’ brazing filler metals. The stop-offs can be used on any ferrous or non-ferrous base material, except for reactive metals such as titanium and zirconium and their alloys. They work in both vacuum and controlled atmosphere brazing.
Three stop-off brazing products are available. BrazeLet Stop-off 10 is recommended for general brazing applications, and especially for application on fixtures. It can be applied by brushing, dispensing or spraying. BrazeLet Stop-off 11 has the same properties as BrazeLet Stop-off 10, but is specifically designed for application with a marker pen. You can read more about BrazeLet Stop-off 11 pen here. BrazeLet Stop-off 20 is recommended when the best surface finish after brazing is needed. This stop-off brazing product is particularly easy to remove after brazing.
All three BrazeLet Stop-offs are odourless and completely water-based. Höganäs’ stop-off brazing pen is refillable, which decreases your costs and offers a more sustainable use.

BrazeLet Stop-off 10
Höganäs BrazeLet Stop-off solutions act as a barrier to the flow of molten brazing filler metals. They should
be used when the flow of the molten brazing filler metal must be contained or redirected due to tolerances,
following assembly steps, and even to prevent brazed parts from bonding to their furnace fixtures.
BrazeLet Stop-Off 10 is recommended for general brazing applications, and can be used with any of Höganäs BrazeLet brazing filler metals. With its superior adhesion to the applied surfaces, it is specially recommended for application on fixtures. It can be applied by different methods such as brushing, dispensing and spraying. After brazing residual stop-off can be removed by using a dry or damp cloth. Removal is most efficient directly after the brazing process.
Available in 1 kg and 5 kg containers.
