The powder coating process uses a solvent free dry mix of plastic resins, pigments and fillers that melt and fuse together when heated. The solid particles of coating are electrostatically charged in a spray gun and carried by low velocity air to the surface of the piece to be coated. The electrostatic charge holds the powder particles in place while the part is cured in a 400-degree oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish.
Powder coating is an environmentally friendly process unlike solvent-based wet paint systems. With EPA regulations growing ever stricter, powder coating is fast becoming the technology of choice. Since the powder coating process does not use solvents in any way, VOC emission problems are eliminated.
Powder Coatings resist cracking and peeling and are extremely abrasion, corrosion and chemical resistant. The performance characteristics of powder coating match or exceed the characteristics achieved from conventional solvent-based coatings.
Powder Coatings are available in a large variety of colors, metallics, textures and special effects. PPC can assist you in choosing the correct coating and color for your application.
Any metal object that can hold an electrostatic charge and withstand the heat of the curing process can be powder coated. Powder can be applied to intricate surfaces and still maintain a uniform finish across the entire piece. Powder coating is ideal for items such as:
- Industrial Fabrications
- Architectural Signage
- Trade Show Exhibits
- Metal Fencing and Railings
- Retail Displays & Fixtures
- Patio Furniture
- Tree Stands
- Motorcycle Frames Wheels & Parts
- Automotive Frames Wheels & Parts
- Off Road Vehicle Frames & Parts
- Bicycle Frames & Parts
- Antique Beds, Gliders & Chairs
- Large Bird Cages
High temperature masking can be applied to special surfaces such as threads or high tolerance areas to keep them from being coated. We also use high temperature silicon plugs for threaded holes or shafts
The high oven temperature makes the use of plastic and resin body fillers problematic. Often the powder will not bind to a filler's surface causing bubbles in the coating. To be safe, fill any depressions with a torch using brass or welding rod as fill. You can also allow PPC to fill any depressions with out special filler.
Clear powder coating serves the same purpose as clear coat wet paint. It protects the underlying finish and adds depth and luster to the surface. Clear powder coat is applied as a second coat and shot while the piece is still hot. Then the piece is returned to the oven for a second curing process. Use clear powder coating on any piece that exposure to elements could cause it to fade or be subject to damage.
Our quoted prices do not include any freight charges. We have the recommend UPS and generally use them unless you request another method of shipping.
There are several things that you need to be aware of with new ceramic coatings. We will give everyone a sheet with their parts detailing the "Do's and Don'ts" to properly break in their new ceramic coating.
The coating runs between 2 and 4 mils thick. If there are threaded holes on the part, you may have to re-tap them prior to installing the part. This will insure a proper fit of the threaded fastener. If the threaded area is critical, then notify us when the parts are delivered so we can mask off these areas to protect them from the ceramic coating.
Yes. If we are coating over chrome, the chrome must be in good shape. If it is flaking off, we recommend having the chrome removed prior to delivering the parts to us. This will ensure a good base for a long lasting product.
Most ceramic coatings consist of the same base materials. The difference is HOW these materials are applied. At PPC, we have a long history of quality and maintain our certification in this area. We also have a warranty to stand behind our coatings.
