This MG Chemicals 421 Liquid Tin is a clear immersion tin for coating a copper substrate or solder deposit with a dense tin coating. It tinplates copper circuits on PC boards in 5 minutes or less at room temperature for immediate soldering capability. It leaves a dense coating, and it contains no co-deposited organics for strong resistance to oxidation. Liquid Tim can be readily soldered, has a long shelf life, and does not require mixing or diluting. Residues can be rinsed away with warm water for easy cleanup. Liquid Tin will cover 3600 square inches of board per half liter of solution, and it is Restriction of Hazardous Substances (RoHS) compliant. This solution is strongly acidic; protective gloves, clothing, and eye protection must be worn.
