Power Coating is A great way to Finish Your Project

Updated on May 15, 2014

A Do-it-Yourselfer

You have completely stripped your car. You have removed all the parts and taken the engine out of the vehicle. You have essentially destroyed your old car, and are now preparing to rebuild your new dream car. All of the surfaces on the parts of the car are metal and/or plastic. You are caught in a car-nun-drum. You want to add color and style to your car, but are left to wonder whether you need to buy new parts, or can you use the parts you have and change their coating. You are a handy guy, mechanically inclined, one who likes to do his own work, and complete his own projects. You need to do research on how you can do it yourself in your garage. What you find is informative, amazing, and comforting, as you know that you can now complete your project on your own.

Powder coating is the answer

As you look at the various methods for applying color to your metal and plastic surfaces, you discover powder coating. Powder coating is a dry based powder application, which does not use paint, but dry powder particles to create the coating on the surface of the object. The dry powder does not require any solvent to keep the powder in a liquid form. The dry powder is applied electrostatically and cured with high h eat. It can be applied in one of two ways, thermoplastic, which allows movement to the object after coating, or thermoset polymer which is a more rigid and durable, used for objects that will not be changed or reshaped. The powder coating technique is used to create a harder surface than conventional paint, goo d for use on metals or plastics, such as the items located in your vehicle.

How can you do it?

There are usually three separate parts during the application of dry powder. First you need to pre-treat the metal or plastic object. This requires extensive cleaning, degreasing, and removal of all excess gunk and grime from the surface of the object. This can be accomplished with chemicals, such as acetone, for smaller objects, and a sandblaster to mechanically remove the debris from larger items. Next, you need to apply the powder. The most common method is using a powder gun which sprays the powder on the object. The gun gives an electrostatic charge to the powder as it is projected from the gun onto an object which is grounded with no charge. This allows the powder to adhere to the surface of the metal or plastic object. The final stage is to cure the object. This requires heating in an oven, or applying direct heat from another source onto the object. Normally, it is heated at a temperature of 390 degrees Fahrenheit for approximately 10 minutes. This allows the powder to hardened and create a smooth coating across the object.

Happy with the finished product

After you use powder coating on your metal or plastic surfaces, you are ready to reassemble your vehicle. As you slowly connect all of the parts of your car, you will see a coherent style and design taking shape, one which you laid out in your mind before you began the process. When you have completed the project, you will look at the finish on your vehicle and be overcome with happiness.
