What is powder coating?

So, you've heard of it, but you're not quite sure exactly what powder coating is. According to the Powder Coating Institute's web page, "Powder Coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products that are used by both industries and consumers. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high - quality and attractive finish."

There, so now you know! Or do you?

Powder coating guns apply a negative electrostatic charge to the flour-fine powder (that magical mixture of "pigment and resin"). This charge is high voltage; up to 100,000 volts on industrial guns, but fortunately,very low amperage (the amps are the part of electricity that can really hurt or kill you). Since the powder is made of resins, we know that it falls into the general classification of "plastics". As a member of the plastic family we know that it is a poor conductor of electricity. So, once it is charged it gives up that charge very reluctantly. That is what makes it "cling" to the substrate being coated. The negative ions in the particle slowly fight their way to the positively charged substrate. This slow flow of ions from particle to substrate is what makes it hold on.

Why is Powder Coating Better?

More durable than paint

Protects the environment
No solvents are needed as in liquid processes.

More economical

By eliminating solvents, companies are able to comply with the regulations of the U.S. Environmental Protection agency.

Where is Powder Coating Used?

Everyday Products -
Such as lighting fixtures,electrical components, farm equipment, tractors,golf clubs and carts, snowmobiles, bicycles, display racks, shelves, store fixtures, vending machines,Marat furniture, thumb tacks, paper clips, cribs, toys, lawn mowers,barbecue grills, patio furniture,garden tools,tool boxes, the list goes on.

Motorcycles-
Frames, wheels, accessories, exhaust and any component that is metal.

Automotive-
Because of all the reasons mentioned in "Why is Powder Coating Better?" it transforming the automotive industry. In the "aftermarket" parts can be re coated with powder with an endless variety of colors.

Architecture/Building-

Aluminum extrusions used for window and door frames, light poles, guard rails, signs, posts and fencing to name a few.

The boom has just begun!
