What Is Powder Coating?
Powder coating is an advanced method of applying a protective, tough, colorful finish to metal objects. A finely ground mixture of pigments that are positively charged are applied to an electrically grounded negative surface. Then they are fused together into a solid coating. Cured in an oven at over 400 degrees, the results are a high-quality, long-lasting, scratch-reisistant finish.
Why Is It Environmentally Friendly?
Powder coating is recognized as an environmentally friendly process because it doesn’t rely on solvents or chemical carriers like traditional wet-paint systems. Because powder coating relies on the electrostatic charge to hold the paint to the work piece, powder coating eliminates VOC emission problems.
How Durable Is It?
Powder coatings are very resistant to cracking and peeling and provide very high abrasion, corrosion and chemical resistance. These attributes vary according to the specific application and paint choice. Powder coatings typically meet or exceed the finish performance characteristics of conventional solvent based wet paint coatings.
What Can Be Powder Coated?
Typically any metal object that can hold the electrostatic charge needed to affix the sprayed powder and can tolerate the high heat levels of the curing process. Mild steel, galvanized and electroplated steel, aluminum, stainless steel and most other steel alloys can be powder coated.
Can Automotive Projects With Plastic Or Resin Body Fillers Be Safely Powder Coated?
No. The high curing temperatures required for powder coating wreak havoc with plastic or resin automotive fillers such as Bondo. The powder won’t typically bind to the fillers surface which leads to bubbling and other surface imperfections in the paint. We recommend filling any surface irregularities with brass or welding rod as fill instead of traditional automotive fillers.
