PPG Industries’ industrial coatings business has introduced Duranar powder coatings for architectural aluminum. The coatings are an extension of the existing line of Duranar liquid coatings and are engineered for monumental architectural applications such as building panels, curtain walls and storefronts.
Made using Kynar 70-percent polyvinylidene fluoride (PVDF) resin technology, Duranar powder coatings have the environmental benefits of a zero-VOC powder coating.They also have the same durability, color and gloss retention, and chalk, corrosion and stain resistance as Duranar liquid coatings, outperforming competing powder coatings manufactured with similar resins.
Duranar powder coatings are formulated with color pigmentation that is screened extensively and has a 40-year track record of performance and durability on thousands of buildings around the world, in virtually every type of climate. Also, Duranar powder coatings are applied using a proprietary, multi-coat system with a primer and a hard powder-film topcoat. This produces a thermoplastic bond between the coating and the metal substrate that delivers unequalled protection, adhesion and colorfastness, even in extreme environments such as seacoast exposure.
Duranar powder coatings are available exclusively through members of the PPG Certified Applicator Program (PPG/CAP), an elite group of commercial coating applicators certified by PPG to apply high-performance fluoropolymer coatings to aluminum architectural components.
As with Duranar liquid coatings, Duranar powder coatings can be formulated in small batches, enabling architects to specify custom colors economically, and they are covered by the same 20-year warranty.
“With the addition of Duranar powder coatings, PPG now offers coatings that meet all relevant AAMA standards in both liquid and powder form,” said Henry Lowman, PPG director, extrusion products. PPG also manufactures Coraflon and Envirocron powder coatings and Duranar, Coraflon and Acrynar liquid coatings for architectural metals. Lowman said PPG can work directly with architects, engineers and curtain wall consultants to help select the right liquid and powder coatings for their projects.
