Pretreatment Specialties – For a Better Effect

Pretreatment processes such as pickling additives ameliorate the effect on surfaces. Atotech pickling additives are unique blends that can be added to mineral acids.
To protect plating parts from a micro-thin and invisible oxide layer, they have to be activated. Atotech products adapted to any materials enhance the activation process with a reduced etching effect before electroplating.
