The surface treatment industry is not only directly related to the galvanic sector but an important role is also offered by a number of technologies that, even if they don’t coat the materials with other metals, still in any case use other techniques and other chemicals to impart functional and also decorative performances to the surface of product and which is sometimes the best technical and economic compromise on an industrial scale compared to galvanic treatments. These are processes that use resins and pigments of various kinds, in liquid or solid solution (powder), with or without the use of electric current, capable of covering the object in automatic or manual mode depending on the requirement.
