PPG Celebrates Anniversary of PVDF Coatings

PPG has announced that it is celebrating the 50th anniversary of DURANAR coatings throughout 2017, commemorating the introduction in 1967 of the polyvinylidene fluoride (PVDF) coatings for metal building components.

Over the past half-century, Duranar coatings have been specified by architects to protect and enhance architectural landmarks, such as the Empire State Building in New York, the Louvre Pyramid in Paris, Shanghai World Financial Center in China, Petronas Towers in Kuala Lumpur, Malaysia, and the Rock and Roll Hall of Fame in Cleveland.

PPG has refined Duranar coatings since its introduction to meet evolving aesthetic, performance and sustainability demands of architects and building owners. Advances have included adding metallic flakes and other effects for appearance options; incorporating ULTRA-COOL infrared-reflective pigments to help reduce building-cooling loads; and formulating Duranar powder coatings, which earned PPG a R&D 100 Award recognizing the coatings’ ability to reduce volatile organic compound (VOC) emissions and economize production of custom-colored powder coatings.

Brian Knapp, PPG director, coil and building products, said Duranar coatings have been popular with architects and building owners for their blend of aesthetics, reliability and performance. “Duranar coatings can be formulated to provide a range of colors and effects, giving architects an unlimited design palette,” he says. “They also feature a chemistry developed and refined by PPG that has delivered decades of color retention and chalk and chemical resistance, even in seacoast and industrial environments.”

Duranar coatings are formulated with PPG resins and pigments in combination with standard KYNAR 500 or HYLAR 5000 PVDF resins. In fact, PPG helped popularize and improve PVDF coatings technology by licensing Kynar 500 resin, which was originally commercialized by Pennwalt Corp. in the mid-1960s. PPG remains the original and continuous licensee of this PVDF resin, which has become an industry standard.

PPG’s formulation for Duranar coatings creates molecular bonds that render the material almost impervious to the effects of continuous ultraviolet (UV) exposure, as well as other environmental and atmospheric hazards such as salt air, humidity, high temperatures and acid rain. In fact, many of the original trial panels coated with Duranar products PPG developed 50 years ago are still enduring exposure testing in South Florida.

As part of the anniversary celebration, PPG will highlight Duranar coatings in trade-show displays throughout the year, offering customer promotions and giveaways. PPG also will introduce a web portal featuring images and descriptions of buildings finished with Duranar coatings, as well as articles, white papers and other educational materials.
