Powder coatings have become a favorite over liquid coatings in applications for both industrial and consumer related markets. Some advantages of powder coatings are that they have been proven to be resistant to chipping, fading, scratching, and wearing when compared to liquid coatings. Powder coatings can also be applied over a wide range of thickness with out running or sagging. Environmental advantages have driven more demand to using powder over liquid because powder coatings do not use solvents; therefore it prevents the release of any volatile organic compounds (VOCs) into the atmosphere.
Although the advantages outweigh the disadvantages of powder coatings to liquid coatings, there are still some limitations on the technology. While it is relatively easy to apply thick coatings which have smooth texture-free surfaces, it is difficult to apply smooth thin films. Also powder coatings may break down when exposed to uv rays between 5 to 10 years.
