The difference between ETP and TFS

Feb 22, 2023

Appearance: ETP has a bright silver-white metallic luster, while TFS has a darker luster;
Corrosion resistance: The tin coating of ETP can provide a certain corrosion resistance, but the chromium coating of TFS is extremely thin and basically does not provide corrosion resistance, so TFS is not suitable for long-term storage;
Paintability: The adhesion between TFS surface and paint is better than that of ETP
Weldability: TFS has no self-welding capability, so it cannot be used to produce three-piece cans, only top and bottom lids or two-piece cans.
