Air-dry products for touch-ups, repair and restoration
PPG’s DURANAR® ADS (Air-Dry System) coatings offer the proven durability of factory-applied fluoropolymer coatings with the flexibility of on-site application. Duranar ADS enables the renewal of weathered curtain walls, window frames and metal facades without costly panel replacement using a variety of application methods, including brush, roller or spray. This innovative system combines decades of PPG expertise in high-performance coatings with advanced air-dry fluoropolymer technology, ensuring exceptional resistance to ultraviolet radiation, chalking and environmental degradation.
Developed for touch up of both powder and liquid coatings, Duranar ADS can be used on FGIA/AAMA 2603, 2604 and 2605 factory applied coil and extrusion coatings. Its ultra-durable chemistry provides long-term performance in even the harshest climates. The system is available in a wide range of colors, glosses and effects—including solids, metallics, micas and color-shifting pigments—providing architects with unparalleled design freedom while maintaining the integrity of the building envelope.
Beyond aesthetics, Duranar ADS supports sustainability goals by extending the service life of existing structures and reducing the environmental impact associated with replacement materials.
For more than half a century, PPG has set the benchmark in architectural coatings, and Duranar ADS continues that legacy by bridging the gap between factory-applied durability and field-applied convenience.
