g/l nickel 15.0 g/l sodium hypophosphite
after
10 to 20 minutes of coverage of with zincate treated aluminum
prevents
zinc pollution in electroless nickel bath
thus
bath stability of electroless nickel baths improves
longer
life span of electroless nickel baths
minimization
of problems in quality - for example blisters
good
adhesion of following layers
pH
correction with 500 g/l KOH or 500g/l K2CO3
