产品优点︰ Basotronic 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.
Basotronic 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.
