This picture shows the process of powder coating.
- A polymer resin, a pigment and some more ingredients are melted, mixed, cooled and ground into a uniform powder.
- This powder is sprayed on the polished metal surface by electrostatic spray deposition (a method in which the particles of powder are given an electric charge) that makes a uniform coating on the substance.
- Once completely coated, the object is then heated, which results in the formation of long cross-linked polymeric chains.
- This coating is highly durable, hard and attractive.
- It can be done on plastic and medium density fibre board as well.
