Kester 282 Flux-Cored Wire Product Overview:

Alloy: Sn63Pb37

Core Size: 66

Flux: 3.3%

Kester 282 Mildly Activated Rosin Flux Core consists of high quality Grade WW rosin to which a very small amount of an extremely effective activating agent has been incorporated. 282 is classified as Type ROL1 flux under IPC ANSI/J-STD-004 Joint Industry Standard. It was formerly classified as Type RMA per MIL-F-14256. 282 Rosin-Cored solder has been developed for use in the electronics industry where a more active flux than plain rosin is required but where highly activated fluxes are considered potentially conductive. Rosin Core 282 has particular application where difficult assemblies are to be soldered but the flux residue must be electrically inert.

Performance Characteristics:

• Non-corrosive, moisture and fungus resistant, and non-conductive
• Low residue
• Classified as ROL1 per J-STD-004B

Cleaning

Since the rosin residue is dry and practically inert after soldering, the surface is actually insulated for atmospheric corrosion. Residue removal is usually not required, but, if necessary for appearance or utility reasons, the rosin residue can be completely removed with Kester 5240 Rosin Residue Remover.
