Kester 245 was developedo complemenlowesidue liquid fluxes being used byhe electroics industry. The chemistry is based osome ofhe same principleshahave beesafely used for years imildly activatedosifluxes. The use of 245esults ivisually acceptable assemblies withoucleaning, yesoldering quality and efficiency is comparableohaobtained with mildly activatedosiflux. 245is classified asROL0 per J-STD-004. 245 is Bellcore GR-78 complia.
Kester 275 No-CleaFlux for cored solder wire was developedo provide superior weing performance for hand soldering ithe electroics industry. The chemistry is based osome ofhe same principleshahave beesafely used for years imildly activatedosifluxes. The use of 275 No-CleaFluxesults iaextremely clear post-solderingesidue withoucleaning. The unique chemistry i275 was also designedoeduce spaering commoto moscore fluxes. 275 cabe used for both lead-free and leaded soldering. 275is classified asROL0 per J-STD-004.
