Question

Electrostatic spray deposition is the process involved in ________.

• A. anodizing
• B. brick construction
• C. powder coating
• D. sintering

Answer 1

The correct option is C powder coating

Electrostatic spray deposition is a process involved during powder coating.

In this method, a polymer resin, a pigment and some ingredients are melted, mixed, cooled and grounded into a uniform powder. This powder is then sprayed on the metal surface by electrostatic spray deposition (ESD). This results in a formation of a layer that helps in the prevention of rusting.
