Corrosion Resistance After Painting Electrolytic Tin Plate For Tin Can SPTE Tinplate

The electrolytic tinplate used to make tin cans has excellent corrosion resistance after coating, which can meet the needs of different industries for packaging materials, such as food packaging and chemical product packaging industries.
Characteristics of electrolytic tinplate
1. Good corrosion resistance: The tin layer can prevent the metal substrate from contacting the external environment to a certain extent, thereby reducing the occurrence of corrosion.
2. Dense tin layer: The electrolytic tinning process makes the tin layer uniform and dense, which can better resist the penetration of corrosive media.
3. Good bonding with coatings: The surface of the tinplate can be well combined with various coatings to form a solid protective layer and improve the overall corrosion resistance.
The role of coating
1. Isolation effect: The coating forms a continuous film on the surface of the tinplate, which further isolates the metal from the external environment and prevents the intrusion of oxygen, moisture, corrosive gases, etc.
2. Both beauty and protection: Coating can not only make the appearance of the tin can more beautiful, but also provide additional protection and extend the service life of the tin can.

Application:

Tinplate is widely used for the packaging of products. Such as food cans, beverage cans, pet cans, closures,general line cans and so on.
