PPG Industries‘ coil and building products coatings group announced that it will reintroduce DURANAR ADS (air-dried system) fluoropolymer coatings this summer, three years after the products were withdrawn from the market.
This next-generation line of Duranar ADS coatings, based on a newly-formulated fluorinated copolymer resin combined with PPG proprietary chemistry, is designed to repair fluoropolymer coatings on architectural metals damaged during production or after field installation. In addition, these high-performance coatings can provide a wide range of color options for manufacturers and contractors in solid, metallic, pearlescent and infrared-reflective (IR-reflective) pigment technologies.
Brian Knapp, PPG manager, coil and building products coatings, said the reformulated products will fill a specific demand that has been unmet since first-generation Duranar ADS coatings were discontinued. “Other than acrylic lacquers, which are not very durable, there has not been a user-friendly product available for touching up fluoropolymer coatings on products such as window frames, door frames, roofs and metal wall panels marred during fabrication or installation,” he explained.
Because of its single-component formulation, Duranar ADS coating has the flexibility to be applied by fingernail brush for small touch-ups at the end of a production line or to be spray-applied in the field to repair or refurbish weathered metal roofing or siding panels.
