Kester Solder Wire Shelf Life

I bought this after reading the following from kester site.

Kester solder wire shelf life. The shelf life of c hemical products will vary based on the chemistry of the formula. When stored in a dry non corrosive environment between 10 c 40 c 50 104 f the shelf life of wire may be nearly indefinite. This is not a procedure to suggest the wire has been re certified by kester.

Kester 275 no clean flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. It is comprised of 95 percent tin and 5 percent antimony or sn95sb5. 031 diameter 66 core. Storage must be in a dry non corrosive environment between 10 40 c 50 104 f.

Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. It is simply a means to see if the wire still performs to the customer s needs. Kester 44 rosin flux is an activated rosin formula for use in flux cored solder wire. The shelf life of cored solder wire is based on the chemistry of the flux core and the protective alloy covering of the wire.

The use of 275 no clean flux results in an extremely clear post soldering residue without cleaning. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. Other alloys have a shelf life of three years from date of manufacture. 361 f 183 c lead free.
