Powder Coat Paint
For aluminum metal finishing, the main difference between a liquid paint and powder coat paint is that a solvent is not required when working with powder coat. The coating is applied electrostatically and then cured, in an oven, to allow the coating to flow and form a "skin" on the aluminum metal. Powder coat systems, when applied properly can have the same performance benefits provided by their equivalent liquid paint counterparts.
Under normal conditions, a standard 1-coat powder coat system is sufficient, but in highly corrosive applications, such as coastal regions or industrial atmospheres, a 2-coat powder coat system may be required. Powder coat is sometimes used to create a harder finish that is tougher than traditional liquid paint systems.
Powder coating has many advantages for architectural applications. Sustainable buildings and low-emitting products have become more popular over the last few years making powder coat a go to for environmentally conscious or "greener" construction projects. The powder coating process is generally more environmentally friendly, uses less power, emits zero or near zero volatile organic compounds (VOCs) and the powder can be reclaimed during the application process. The U.S. Green Building Council, through the LEED project, is an industry leader in its commitment to sustainable green building initiatives.
