Advantages & Benefits Of Powder Coating
In North America, powder coating process is the quickest growing technology in adding finishes to products, and reflects more than 10% of all industrial based finishing applications. Learn more about the advantages of powder coating below:
It is More Durable
Powder coating provides businesses, consumers, and industries a long-lasting, economical, and durable finish with a range of color options available for nearly any type of metal. In addition, a powder coated surface will be more resistant against scratches, chipping, wear, and fading compared to other type of finishes. There is nearly an unlimited selection of colors, including, glossy, high-gloss, flat, fluorescent, candies, clear, hammer toned, iridescent, glitter and wrinkle which are available. The color will remain vibrant and bright much longer than other finishes too. The selection of textures range between a smooth surface to matte or wrinkled finishes, then there are the rough textures crated to hide imperfections in the surface.
Protecting the Environment
In addition to powder coating providing a great finish, it is better on the environment compared to liquid painting finished that consists of solvents that are known to be pollutants of volatile organic compounds, also referred to as VOC’s. However, powder coating does not contain any solvents, and it only releases very negligible amounts of VOC’s, if any within the atmosphere. This means that finishers no longer have a need of purchasing and maintaining expensive equipment for pollution control. Read powder coating vs painting & which one is better.
It Can Save Money!
By eliminating VOC’s while reducing waste will save money in the long-run while assisting companies in remaining in compliance and economically within U.S. Department of Environmental Protection Agency regulations. In addition, a key element within the growing powder coating market has focused on implementations of the control of stringent air pollution legislations that have been passed in the last 30 years.

Powder Coating Processes:
Powder coating processes vary by the type of material being applied; however, they can generally be divided into four functions:
- Preparation of the surface
- Application of the powder
- Heating of the part
- Curing of the coating
STORAGE
- Under dry conditions ,good ventilation at a temperature not exceeding 30 C,humidity < 60%.
- Storage period recommended should not exceed 12 months,in case exceeding 12 months without affecting their free flowing properties, the powder will still have optimal characteristics.
- Should be protected from excessive heat,humidity,water and contamination with foreign materials such as powder, dust, dirt, etc.
- Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture
