Architectural Powder Coat Finishes
The powder coating industry has made steady advances in technology to reach architectural performance requirements. Many powder coats are available that meet AAMA 2604 and AAMA 2605 specifications; there are also some Kynar 500 based powders that have excellent performance and sustainability. The leading brands of high-performance powder coat include PPG Duranar and Akzo Nobel Interpon as well as Sherwin Williams, Spraylat, TCI and Tiger Drylac powder coatings.
Powder coatings are made without solvents. As a result, they emit zero volatile organic compounds (VOCs) when they are manufactured or factory-applied to a metal substrate.
Because powder coatings lack solvents, they emit zero VOCs. Liquid coatings are made with solvents that contain VOCs, but their VOC content is off-gassed and cured at the factory before arrival on the building site. This process makes both Kynar 500® PVDF resin-based paint coatings and powder coating an excellent choice for any building.
Powder coat is an excellent option for high-touch products such as handrails and entrances because of its hardness and scratch-resistance. The hardness of powder coatings is due to the raw materials used in their manufacture. Because they must be solid at room temperature, the resins used in powder coatings are heartier than those suspended in their liquid counterparts. As a result, powder coatings naturally produce thicker film builds that are harder and therefore, more resistant to scratches, mars, erosion and other detriments associated with high-touch, high-traffic applications.
