The unique chemistry in 275 was also designed to reduce spattering common to most core fluxes. 275 can be used for both lead-free and leaded soldering. 275 is classified as ROL0 per J-STD-004. Lead Free: Yes.
278 is classified as Type ROL0 flux under J-STD-004B specifications. The flux residues are non-corrosive, non-conductive and do not require removal in most applications under normal conditions of use.
An outstanding performance feature of this flux is the “instant-action” wetting behavior. 44 is classified as ROM1 per J-STD-004. The flux residues are non-corrosive, non-conductive and do not require removal in most applications under normal conditions of use.
