Stannous Sulfate Tin Plating Brightener
Stannous sulfate tin plating brightener is formulated for acid tin sulfate baths to produce bright, smooth, fine-grained tin deposits with excellent solderability and low contact resistance for electronic and food packaging applications. The brightener system stabilizes the stannous ion against oxidation to stannic ion and controls grain structure to produce matte or bright tin as required. Bright tin plating is widely used for electronic component terminations, food can linings, and decorative tin applications.
