NOCOLOK® Flux Paste is a flux paste specifically formulated for providing a viscous homogeneous mixture of NOCOLOK® Flux (15 – 50%) in an organic carrier for brazing aluminium cladded interfaces where traditional water based fluxing is not suitable. Typical applications include but not limited to: interior tube seams (B-tubes), snap over joints (clinch tubes), tube-to-header joints, internal turbulators. The paste can be dispensed manually by brush or syringe or with automatic dispensing equipment. The paste can be used in both furnace and flame braze process. CsAIF4 can be added to accommodate materials with Mg of up to approximately 0.5 % in furnace brazing. This refers to the combined Mg-level of both components to be joined.
