PURPOSE:To prevent corrosion of solder powder and oxidation of base metals and to improve brazing workability by mixing PE and org. gelling agent respectively at prescribed % with specific wt.% of n-heptane to form the titled binder. CONSTITUTION:The binder for paste solder is obtd. by mixing 40-80% PE, by weight, with 20-60% n-heptane, adding 0.25-3%org. gelling agent further to the mixture, mixing and agitating the mixture and heating the same. The sepn. and corrosion of the solder powder during storage are prevented and the corrosion of the base metals when the solder is coated on the base metals is prevented as well if the paste solder is prepd. by adequately mixing and agitating the solder powder and this binder. The splashing of the binder during brazing and the formation of residue are prevented and, therefore, the brazing workability is improved.
