JOHNSON'S C-71-2 CORE BAKING FLUX

Johnson's C-71-2 Core Baking Flux is proven reliable for oven baking of copper or finds to solder coated tubes in radiators and heat exchanger applications.   The improved wetting actions on C-71-2 offers increased wetability yet does not remain behind to cause discoloration of the core. This flux vaporizes during the heating cycle leaving a good clean surface so radiators are ready for header dip soldering.

C-71-2 Flux Concentrate should be diluted with eight (8) parts clean water to one part flux. Too high concentration of this flux can reduce solder flow, as can too low a concentration. Make any changes in dilution of the flux and water cautiously from the recommended mix.
