Storage and Handling of Tin Lead Solder Bar 55/45

1. Store the solder bars in dry & non-corrosive place, avoid direct sun-light.

2. The solder bar has an indefinite shelf life when stored in a dry, non-corrosive environment. The surface may lose its shine and appear a dull shade of gray. This is a surface phenomenon and is not detrimental to product functionality.

3. Make sure you select a proper flux to go with the solder bar because all bars are without flux, XF Solder bar 55/45 are compatible to most of the flux produced by major brands.

4. Read MSDS & TDS of solder bar 55/45 (Sn55Pb45) before soldering
