278 Flux-Cored Wire

Kester 278 Flux-Cored Wire with Innolot Alloy is a halogen-free wire optimized for high performance applications, such as under-the-hood automotive. 278, with its fast wetting and low spattering, performs admirably when benchmarked against conventional halogen/halide-based systems, enabling its use in drag soldering and minimizing cycle time in robotic and manual soldering. The use of 278 results in a clear post-soldering residue without the need for cleaning. 278 is classified as Type ROL0 flux under J-STD-004B specifications. 278 is halogen-free and halide-free, conforming to the strictest requirements of IEC 61249-2-21, JPCA-ES-01 and IPC-410B specifications.
