Binder poisoning
For particle-based brazing technologies, alloy particles are attached to the metallic surfaces with binders. When the assembly heats up, the binder breaks down and fumes into the inert CAB atmosphere
If these binder fumes reach the brazing zone, they contaminate the brazing process - often due to oxidation or carbon deposits
This can render the braze alloy ineffective
We have successfully designed and implemented special technologies in order to control binder fumes to prevent binder poisoning
