Product Characteristics Excellent for solderability test procedures specified by military and commercial industries Designed for high thermal stability and superior solderability. Kester # 186 is available in 18, 25 or 36 percent solids formulations. Kester's active, non-corrosive rosin type flux. Used on surfaces which are more difficult to solder. These active formulations are designed for high speed wave soldering applications. Varied solids content and halide activity available
Compliant specifications ANSI/J-STD-004 ANSI/J-STD-004 ANSI/J-STD-004 ANSI/J-STD-004
