Why Is Powder Coating 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.
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.
What About Sensitive Areas Like Threading or Clearance Holes That Can't Be Painted? Special high temperature masking can be applied to most surfaces such as threading or tolerance areas to avoid coating. We may also use high temperature silicone plugs to protect galleries, threaded holes or shafts as needed.
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.
What Is Clear Powder Coating And Why Is It Important? Clear powder coating is similar to clear coated wet paint. The clear powder coat protects the pigmented powder coating underneath and helps to add depth and sheen to the finished surface. We recommend a clear powder coating over any powder coated finish containing metal flakes. This helps to protect the base powder coat layer from the additional stress induced by the metal flakes and their reflective properties.
What type of powder coating should I choose? Powder coatings are available in four basic types, each offering different performance attributes. Epoxy for the best corrosion protection. Hybrid(s) typically offer the best chemical and solvent resistance. Polyurethane offers flexibility and hardness for suited for moving parts. Polyester for the highest exterior stability and performance.
