UCON™ Solder Assist Fluid 26 is a biodegradable, low toxicity polyalkylene glycol (PAG)-based chemical specially designed for use in solder reflow fluids, fluxes, fusing fluids, and other process fluids where superior water solubility and a wide temperature profile is critical.
UCON™ Solder Assist Fluid 26 (SAF-26) is a low-viscosity, water-soluble PAG fluid specially formulated with performance additives to improve your product's thermal stability and flash point. This high-performance solder assist fluid is suitable as a component in reflow fluid, flux, and fusing fluid soldering processes. It provides good temperature and oxidative stability, in addition to excellent water washability to prevent film or deposit formation.
The high flash and fire points of UCON™ SAF-26 make it ideal for use in printed circuit board manufacturing and assembly. UCON™ Solder Assist Fluid 26 has a viscosity of 90 cSt at 40°C.
