what is the steel drum coating resin? take a look

steel drum is one of the traditional containers, the application has a history of more than one hundred years, in today, the packaging technology changes with each passing day, the application of steel drum in some aspects has been partially replaced by plastic or composite, but because the steel has excellent comprehensive performance, and rich resources, so the steel packaging container still maintains vitality, the application form is more diverse. According to the surface coating composition and use of different, steel drum packaging is divided into the following materials:

1, cold rolled low carbon sheet

2. Hot-rolled low-carbon thin steel plate

3. Tin-plated steel sheet

4. Chrome-plated steel sheet

, as an industrial product, is 53 gallons or 200 liters of packaging barrels, which are mainly made of the first three materials. If the steel barrel is not coated with paint, in addition to its single and unsightly appearance, it is mainly easy to be corroded, which greatly reduces its service life. In particular, some barrels have to cross the sea during transportation and some barrels are placed outdoors for a long time. In all these cases, the barrels are quickly corroded. In order to effectively save resources, steel drums should be coated with steel drum paint before use. Steel barrel coating, that is, the appearance of the requirements, but also have weather resistance, corrosion resistance and impact resistance requirements, steel barrel coating performance is generally higher.

In the past, the steel barrel coating was mainly amino baking paint, because amino paint has excellent film performance and low price after baking and crosslinking. In addition, the steel barrel has a single shape, which is easy to realize automatic spraying line operation. In recent years, with the strengthening of environmental regulations, oil-based coatings are ready to be replaced by water-based coatings.
