Which of the following describes powder coating?

Powder coating is a finishing process that involves applying a dry powder to a surface and then baking it to create a durable and protective finish. The process starts with the powder, which is typically made of finely ground particles of pigment and resin. When this powdered paint is applied, usually through an electrostatic spray gun, it adheres to the surface due to the electrical charge. The coated surface is then heated in an oven, which causes the powder to melt and cure, forming a hard and resilient coating.

This method is favored for its many advantages, including a thicker and more even coating, enhanced durability, and better environmental performance, as it typically emits fewer volatile organic compounds (VOCs) compared to liquid paint application. The use of baking to complete the process is what distinctly characterizes powder coating, making option B the correct description.
