Powder Coating

Durable Attractive Finishes For Metal Parts

Powder Coating Provides A Combination of Both Durability and Aesthetics

At Defence Coating Systems (DCS), we offer more than just coating services. We provide comprehensive solutions, tailored to enhance the durability, performance, and aesthetics of your products. Our powder coating service is a testament to this commitment. 

Powder coating is a preferred finishing process that provides a more resistant and longer-lasting finish compared to conventional paint. Its application involves using an electrostatic gun to spray powdered polymer onto metal surfaces, which is then cured under heat to form a hard, protective shell.

What is Powder Coating?

Powder coating is like a super-strong paint that's used on metal parts and components. Instead of being liquid like regular paint, it's a dry powder that gets sprayed onto the object using electricity. Then it's heated up so that it melts into a hard shell.

The advantage of powder coating is that it's very tough. It doesn't chip or fade easily, and it's more resistant to scratches and wear compared to regular paint. That makes it perfect for items that are often exposed to sun or harsh conditions. Plus, it's safer than traditional spray painting because the powder doesn't contain any harmful toxins.

Electric Attraction Allows For A Uniform Layer Of Powder

The Application Process

Once the surface of the metal has been prepared and cleaned, the application process begins. The powder, which is typically a type of polymer, is charged using an electrostatic gun.

This charging process gives the powder particles a positive charge, and because the metal surface is grounded, it creates an electric attraction between the powder and the metal surface. When the charged powder is sprayed onto the metal surface, it adheres evenly across the surface due to this electric attraction. This method allows for a uniform layer of powder, ensuring that all parts of the metal surface are adequately covered.

More Robust Than Conventional Paint

The Curing Process

After the application of the powder, the coated part is moved into a curing oven. This oven is heated to a high temperature, typically between 180 and 200 degrees Celsius. The heat causes the powder to melt and form a smooth, liquid layer over the surface of the metal.

As the heat continues to cure the coating, a chemical reaction takes place that causes the liquid coating to harden and fuse to the metal surface. This results in a hard, durable finish that is resistant to chipping, scratching, and fading, making it more robust than conventional paint.

Quality Control Ensures Durability Standards Are Met

Final Inspection

In the coating process's final step, DCS inspects the product for flaws or imperfections, ensuring it meets industry and customer standards. Any products that do not meet the expected requirements are reworked to meet the required quality standards.

Recognising each client's unique needs, we tailor coating systems to your preference, whether matte or high gloss. Our powder coating ensures your products look pristine and endure tough environments.
