The poor adhesion of copper deposited on steel by chemical replacement using a copper salt in acid solution can be overcome by using Ethoquad C/12 in the salt formulation. In the electroplating of copper the brightness can be increased by adding small quantities of Ethoquad C/25 or Ethoquad 18/25 to the plating. |
