The 421 Liquid Tin is a clear immersion tin solution designed to coat copper traces and solder deposits with a thick coating layer of tin. The deposited tin is readily solderable and it extends the work life of circuits by protecting it from corrosion. The excellent corrosion resistance is provided by the pure tin deposit, which is free of co-deposited organics. The 421 ensures good solderability for solder deposits by cleaning them and by making their surface bright and active. ATTENTION! Keep at temperature above 5 °C to avoid unwanted precipitations. If the product freezes, the solution will be ruined.
