A formaldehyde-free chemical bath containing a palladium salt, a nitrogenated completing agent, and formic acid or formic acid derivatives, at a pH of greater than 4 and a process of using the chemical bath for depositing on a metal surface an adhesive, permanently glossy, bright palladium layer with few pores. The metal surface may be pretreated in a cementation palladium bath. The metal surface contains at least one of copper, nickel, and cobalt, as well as their alloys with one another and/or with phosphorus or boron.

palladium layers deposition process

A process is disclosed for the adhesive metallization of synthetic materials, by means of pre-treatment of the synthetic materials and subsequent activation, as well as chemical and, if necessary, galvanic metal deposition, characterized by pre-treating the synthetic materials initially with an alkaline solution of an oxidation agent and then with a metal salt solution.
