What is Powder Coating?
Powder coating is a free-flowing, dry powder. The difference between liquid and powder is that powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electro-statically and is then cured under heat to allow it to flow and form a more durable finish. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is primarily used for the coating of metals & aluminum. Powder coatings emit zero or near zero volatile organic compounds (VOCs), and produce less hazardous waste than conventional liquid coatings.
Powder coating is specified because of its durability, scratch resistance, gloss retention, weatherability, resistance to chalking, the unlimited range of colors, finishes, glosses and textures, the fact that it meets AAMA specifications and because it is an environmentally friendly finishing process, making it an important part of a sustainable or green building project that incorporates low-emitting products.
The new thermosetting Fluoropolymer resin based coatings are designed with the top architectural specifications in mind and warranted towards the AAMA 2605 specifications.

Advantages of powder vs. liquid kynar: Environmentally friendly, solvent free finishing solution for High Performance Architectural Aluminum (no VOC)
No hazardous waste generation in application process EPA recommended finishing system, contributing to further towards the Green Building Initiative of the US government
Higher surface hardness (2 H to 4 H) than common liquid thermoplastic, Kynar based coatings
Better scratch resistance than liquid coatings
Better Taber Abrasion than liquid coatings
Better falling Sand Abrasion than liquid and powder PVDF systems
Higher film surface hardness translates into less chance of damage during Manufacture and installation of coated Aluminum work piece and also better longevity Against mechanical damage (intense use, high traffic areas, windborne abrasives)
Better Nitric Acid Vapor (Acid Rain) resistance in 72 hour exposure to liquid and Powder PVDF coatings translating into better resistance in corrosive atmosphere.
Better corrosion protection than liquid and powder PVDF systems without the need forprimer. Able to meet 4000 hours salt spray resistance in one coat.
No need for primer eliminates labor cost associated with second coat.
Better OUV B-313 Accelerated Weathering color retention than competitive PVDF
Significantly lower cure temperatures compared to liquid and powder PVDF coatings (400 °F versus 475 °F) resulting in less energy consumption.
Thermosetting (crosslinked) coating system as opposed to thermoplastic PVDF system ensures maximum film integrity
Warranted towards the AAMA 2605-02 specifications for minimally 15 to 20 years.
Price competitive to liquid Kynar systems
Recovery and re-use facilitates efficient and higher material utilization
Wider available Gloss range than liquid PVDF coatings (30 to 75)
