Product Description
Kester 5744 Solder Saver
®
is a chloride-free, inorganic white powder formulated to remove dross, the oxide of solder,
from still solder pots and wave soldering machines. Unlike most active reducing materials, 5744 does not decompose to
sticky residues that are harder to remove than the original dross. 5744 has been designed to be low fuming and is stable
at soldering temperatures and has been shown to be effective up to 380°C (720°F). This makes the 5744 a good candi-
date for both tin-lead and lead-free solder baths. Unlike flammable, messy, organic-based solder cover chemicals, 5744 is
a non-flammable powder that remains a solid while it is working and is easily removed from the solder pot after it is used.
Reducing tin oxide back to tin metal will greatly reduce dross scrap and will help keep the soldering pot surface clear of
residues.

Application
5744 must be used on a still solder pot surface. All solder wave pumping and agitation action must be turned off. The pot
temperature should be controlled to 232-260°C (450-500°F). Cover the solder surface with 5744 by sprinkling the powder
on the pot in a thin covering layer, no greater than 6.4mm (0.25in) thick. Slowly mix the salt with the surface of the solder
with a metallic solder ladle or a metal spatula. Allow the salt 10 seconds after mixing to convert the dross back to solder.
Move any dross on the pot into the salt covered surface to covert the dross to metal. When done, remove the dross recov-
ery salt and other dirt residues with a metallic solder ladle or a metal spatula. All of the 5744 should be removed from the
solder surface. 5744 is intended to be used as received.
Storage, Handling and Shelf Life
5744 should be stored in sealed containers. Shelf life is 3 years from date of manufacture when handled properly and held
at -10-45°C (14-113°F).
