Powder Coating vs. Painting a Chassis

Posted on: February 18th, 2014 by byersbushblog

When you are finishing your race car, you have a couple of choices in regard to your chassis.  You can paint the chassis, or you can powder coat it.

It needs to be protected in some fashion so that it doesn’t end up looking rough and beat up.  Typically, we think of paint when we are finishing race cars.

However, powder coating your chassis is a much better choice.

The process of powder coating is pretty simple.  What makes it special is the material that is used.  Finely ground plastic mixed with a pigment to give it the desired color is sprayed on to the surface of the chassis through electrostatic transfer.

Powder coating can be used to treat many different products.  The secret to obtaining a perfect finish when powder coating is the preparation of the item.

The Process

You must have a smooth, clean surface before the powder coat is applied.  For that reason, the object should be sandblasted before the powder coating is applied.

Sandblasting will remove any rust, dirt, debris, or paint remnants from the surface so that it is flawless and ready to receive the powder coat.

This isn’t done just for vanity’s sake; the surface must be clean and smooth in order for the powder coat to properly adhere.

Sandblasting doesn’t just make the finished product look nicer.  It ensures that the powder coat is effective.

Once the chassis has been sandblasted, it must dry completely.  Rather than just allowing it to dry, it should be baked in a large oven.  This ensures that it is completely dry and there is no hidden, lingering moisture.

After the chassis has been dried in an oven, the powder coat can be applied.  The coating itself is composed of plastics that have been ground down into a fine powder.

The plastic powder is mixed with pigments in order to achieve the color that you desire.  It is applied to the chassis using a type of gun that looks a bit like a hair dryer.

The applicator gun gives the powder an electrostatic charge, which keeps the powder in place on the chassis until it is baked in the oven and solidified.

During the baking process, the powder melts and cures.  This creates a very uniform and durable finish on the chassis.

The Advantages

There are many advantages to powder coating.  First of all, it provides a very even and uniform finish.  It can be applied in a wide range and variety of colors.

There is no dripping or running with powder coating, as you might see with paint.  Perhaps most importantly, powder coating provides a durable finish.

It protects and preserves the metal underneath.  The chemicals that you use to maintain your car, like brake fluid, could eat through paint.

Powder coating, however, is resistant to those chemicals.  It won’t be damaged by brake fluid or any of the fluids that you use to care for your car.

Another benefit of powder coating is speed.  When you paint a chassis, it must cure for days before you can touch it.  When you powder coat a chassis, it is ready to go as soon as it has cooled down after baking.

Clearly, powder coating has many advantages.  You can learn more about powder coating your chassis or other item by contacting Byers Bush Powder Coating Inc.
