Kester E-Bar is designed for electrical, electronic and mechanical applications requiring bar solder that meets or exceeds the requirements of QQ-S-571-F, ASTM B32, and ANSI/J-STD-006.

Kester Ultrapure® is made by a special process which controls the inclusion of oxides and metallic and non-metallic impurities. Kester Ultrapure® is the industry standard bar solder for use in high tech electronics applications where lower surface tension and hole filling ability are essential. The purity of Kester Ultrapure® far exceeds the requirements of QQ-S-571-F, ASTM B32, and ANSI/J-STD-006.
