MS2 molten solder surfactant eliminates dross in wave soldering. Available for both leaded and lead-free processes, does not mix with the metal but forms a thin floating layer that covers the entire solder surface except the wave, which it does not disturb. Prevents dross from forming on the surface and immediately converts any dross generated by the wave back into usable metal. Said to reduce solder usage by as much as 40 to 75% and result in other dross-related cost savings. P. Kay Metal, pkaymetal.com Apex booth 2635
