Electrolytic tinning is used to produce tin coatings and is widely used in electronics, due to its high conductivity, and in the food industry, due to its non-toxicity in contact with food. The process can be performed on frames or in barrels. The tin coatings we provide are very bright: a silver-white that persists even in damp environments. The thickness varies from a few μm to 20 μm. The treatment complies with RoHs 2011/65 EU directives.
