How Does Powder Coating Work?

Nothing protects and personalises your vehicle like powder coating. It’s a durable and enduring alternative to traditional paint and withstands chipping, fading and abrasion. But what is powder coating, and how will it enhance your vehicle? The experts at Bump ‘N’ Scuff are here to provide all the guidance you need on powder coating, from the application process to the benefits it can bring to your vehicle and wheels.

What Is Powder Coating?

The clue is in the name: a layer of powder is applied to metal to protect it from corrosion, pitting and rust. The coating consists of polymer resin, flow modifiers and pigments for a fantastic finish that’s thicker than a single coat of paint.

Powder coating can be applied to any metallic surface, provided it holds an electrostatic charge. Once the surface has been pre-treated and prepared, we apply primer. It’s essential not to skip this step, as primer can help the finish last up to four times longer.

Then, once the powder coating is applied, it’s cured for optimal results.

How Does Powder Coating Work?

Opposites attract. That’s the principle behind powder coating. The metal components on the surface are grounded, while the powder coating is charged when sprayed through the coating gun.

The result? An electric field that causes the particles to adhere to the surface through electrostatic bonds, creating a perfect, durable finish.

What Is the Purpose of Powder Coating?

A protective powder coating prevents damage and protects your car against corrosion and impact scratches. The long-lasting colour doesn’t require retouching, and won’t chip or fade.

Even the best engineered vehicle isn’t immune to damage, but using powder coated components is a great way to protect them against the stresses of everyday driving.

Powder Coating for Your Vehicle

Powder coating has multiple applications in aerospace, manufacturing, automotive, and other industries that utilise tough, resistant coatings.

When it comes to your car, a range of parts can be powder coated. We specialise in powder coating wheels, but anything from engine blocks to brake callipers can be customised. Functional coatings can also be used for transmissions, rocker covers, suspension components and the chassis.

Powder coating is highly durable and provides an excellent finish, making it a great choice for restoring a classic car. It’s also solvent free and gives greater protection than paint, especially in the extreme temperatures of the average engine.
