How to Powder Coat Effectively

Posted on: April 30th, 2014 by byersbushblog

Powder coating is a relatively new phenomenon in the metal industry, but has many benefits that have seen it quickly become a real contender against other finishing processes.

It leaves the coated surface both very resistant to corrosion and is better developed to covering and smoothing surface imperfections. How, then, is it done?

Somewhat surprisingly, powder coating is a very simple process that is completed across three stages, after which, with appropriate maintenance, you’ll be left with a finish that will last an incredibly long time.

Stage One: Preparation

Before you begin the coating process itself, the surface you intend to cover, regardless of what it is, requires substantial pretreatment and preparation.

It can be tempting to rush through this aspect of the process, but doing so will result in a sloppy finish, with bubbling, peeling, streaking and reduced resistance to potential lifespan risks have all been observed when the object being coated has been improperly prepared.

Pretreatment equipment should be used to clean your object thoroughly, so that the powder coating can adhere to the object properly. Steam units, dip tanks, and blasting stations are all examples of pretreatment equipment for surface preparation.

Stage Two: Powder Spraying

Once you’ve prepared your surface, it’s time to spray it! This is usually done with a spray gun that gives the powder an electrostatic charge which allows it to adhere to the surface.

This can be a lengthy process, as some paint will require reapplication, but it’s important to take your time. Furthermore, it’s worth finding the right environment to complete the process in.

Enclosed, clean spaces are best, as they prevent debris from getting stuck in the powder coating, leading to similar problems that an improperly prepared surface would have lead to.

Stage Three: Curing

The final stage of the powder coating process is called curing and sets the powder coating onto the object properly, giving it a healthy lifespan, and making it more resilient.

The coated object is cured in an oven between 325-425 degrees F for most powders, where it melts and bonds to form a rock solid finish.

Once the curing process is complete, the powder coat is finished, and the object to which it has been applied is ready for service.
