What Is Powder Coating?
Powder coating is something you’ve likely seen – on cars, motorcycles, handrails, and even light fixtures. Powder coating is a dry finishing process that has become extremely popular since its introduction in North America during the 1960s. Powder coating is used on various products, representing over 15% of the total industrial finishing market. Used extensively in commercial and residential applications, this incredibly durable finishing technique creates a beautiful and customized look that protects for years with no upkeep.
Powder coating, not to be confused with E-Coating, uses a process of electrostatically charged or fluidized dry powder applications. Once applied, it’s baked in an oven to set, bond, and cure the coat.
What Makes Up Powder Coat Paint?
There are slight variations on different products, but they are all very similar. Ingredients include:
- Resin – usually epoxy or polyester.
- Curing Agent – helps during the curing process.
- Additives – there for many purposes, from creating a glossy finish to adding textures and the overall hardness.
- Tints – bring the color to the coating.
- Extenders or Fillers – usually provide extra durability.
You can powder coat anything that withstands high temperatures. Powder coating is a high-quality finish found on thousands of products — including cast iron, aluminum, and steel — you come in contact with each day. Powder coating protects the roughest, most formidable machinery, as well as many of the household items you depend on daily. Powder coated products are more resistant to wear and tear caused by impact, moisture, chemicals, ultraviolet light, and other extreme conditions. This reduces the risk of scratches, chipping, corrosion, fading, and other wear issues. In addition to being durable, powder coating is an attractive choice due to environmental advantages.
