Lutron PVI is a cationic polymer which is used in the electronics industry in the manufacture of printed circuit boards. It enables the walls of through-holes to be homogeneously seeded with catalyst after they have been drilled, which ensures that a uniform layer of electroless copper can be applied. It can either be applied in the desmearing solution itself or subsequently in a separate process. It is usually added to concentrated desmearing solutions at a rate of 1 – 5 g/l.
Lutron PVI is also used to formulate brightener additives for the electroplating industry. It acts as a basic brightener in alkaline zinc electrolytes, and it is particularly effective for improving the adhesion of the plated metal. It is usually employed at a concentration of 0.1– 2 g/l.
