A. Indeed, as said before, a stabilizer has many purposes. The main purpose is in the word itself, to stabilize the solution and prevent if from decomposition. Another reason is for uncontrollable plating, which mostly happens before the bath decomposes. And another reason is, for example 'lead', is to give the coating a more shiny look. When your parts are having a dull grey look, you can add a lead to create a more shiny surface.

A. Hello Cia.

Many proprietary electroless nickel baths have been reformulated in the last few years to no longer use cadmium or lead as stabilizers, because those ingredients can render them not RoHS-compatible. Good luck.
