Lutron Q 75 

Complexing agent for use in the production of printed circuit boards and in the electroplating industry

Application

Lutron Q 75 is used in the electronics and electroplating industries as a complexing agent in electroless copper plating baths at a concentration of 10-30 g/1.

lt is mainly used in the production of printed circuit boards and for plating plastics.

The complexing power of Lutron Q 75 for copper is similar to that of EDTA in the alkaline pH range (pH 12).

It can be applied alone or in combination with neutralized TrilonBS.
