The organic activating system in 837LFWS has a neutral ρH at room temperature and becomes activated at soldering temperature. The 837LFWS is formulated to be effective over a broad preheat range and may be used for both leaded and lead-free applications. It cleans easily with hot or cold water.

The 837LFWS is excellent for prototyping and rework/repair of printed circuit boards. It works well on chip carriers, heat sinks, surface mounted device pads, switches, and sockets.
