Chemguard fluorosurfactants enhance fluxes by improving wetting of low-surface-energy substrates. Fluorosurfactants can reduce surface tension substantially, which allows fluxes to penetrate the very tight spacings increasingly common on electronic equipment. The use of fluorosurfactants in underfills and encapsulants can help eliminate air entrainment and voids.
See Wetting & Leveling Fluorosurfactants product catalog. S-554-100 and S-550 are recommended for "No Clean" flux formulas.For more information, contact specialty chemicals customer support.
