Spray copper plating was further developed and based on new findings became a fixture of very good electric conductive coatings and improved electric conductivity of elements made from poor or non-conductive agents.

The advantage of spray galvanising (ca. 60°C) also in comparison with hot galvanising (at ca.450°C) is that the thermal exposure of the work piece can be disregarded and deformations can be excluded in large surfaces too.
