AMCO 4327, a non-corrosive flux which contains a highly refined resin, activator, and stabilizer, in a blend of alcohol solvents. Designed specifically for soldering handles and nozzles on F style cans and for use in fabrication of 5 gallon square cans which are air tested for leakage. Amco 4327 is the dependable choice; it induces capillary action of solder completely around the joint, forming a strong, permanent bond. Leaves a colorless, non-staining, non-corrosive residue. Designed for use with 505Sn / 50Pb alloy.

AMCO 4938 is a fortified organic flux which contains a highly refined resin activator and stabilizer, in a blend of alcohol solvents. Used for side seams of cans made from tin plate when using lead-free solder, e,g, 95Sn/5Sb.
