gold-bonding bath AC3

Firmly-bonding, hard and non-tarnishing gold deposits are the features of this bath. Beyond the traditionally
plated materials, the bath is also suitable for stainless steels. The strong acid furthermore possesses a
considerable power of activation.

The preplating gold bath AC 3 is used in a traditional type of electroplating unit. The pH-value is adjusted as
necessary with dilute sulphuric acid. A degreased surface is an essential requirement.
