Soft solder without lead or cadmium, for joining stainless steel, steel, cadmium plated steel, copper and its alloys, tin and silver.
The shear strength is almost twice the strength of tin lead solders.
Application temperature up to 100°C (212°F) (At this temperature the mechanical strength is almost 4 times the strength of a Sn Pb solder).
Due to the corrosive flux in the core, Lastek 3102IS shall not be used on electronic circuits or prints.
Joining thin sheets and tubes in stainless steel.
Food industry, toys, refrigerating installation, soft drink equipment, organs.
Tensile strength Rm: 54 N/mm² (7.8ksi)
Temperature: 221°C (430°F)
Electrical resistivity 0.12 ohm.mm²/m (5.10-6 ohms/in/in²)
Joint gap 0.08 to 0.10 mm (0.003-0.004") for maximum strength.
Degrease the parts if strongly contaminated and preheat with soft flame.
Melt the rod on applying the rod along the joint.
Lastek 3102IS can be used with a soldering iron: do not apply the solder on the iron, this will deactivate the flux. Carefully apply the solder onto the preheated workpiece and simultaneously push the iron on the joint.
Remove flux residues with warm water.
Work in a ventilated area.
