What is Powder Coating? Advantages, Process, and Uses

Powder coating is a dry finishing process commonly used on metals and some plastics to give a durable and attractive finish. Unlike traditional liquid paint, powder coating is applied as a free-flowing dry powder and then cured under heat. It offers better performance, long life, and an eco-friendly solution.

How Powder Coating Works:
1.Preparation – The surface is cleaned using sandblasting or chemical treatment to remove dust, rust, or oil.

2.Application – The powder is electrostatically sprayed onto the item. The charge helps it stick firmly to the surface.

3.Curing – The coated item is placed in an oven where it is heated, causing the powder to melt and form a smooth coating.

4.Cooling – Once cooled, the result is a hard, durable, and attractive surface.


Where is Powder Coating Used?
1.Automotive Parts – Rims, bike frames, engine parts.

2.Home Appliances – Washing machines, microwave casings.

3.Furniture – Metal chairs, tables, racks.

4.Industrial Equipment – Pipes, railings, gates, and panels.
