PPG Industries’ industrial coatings business has introduced Duranar powder coatings for architectural aluminum. The coatings are an extension of the company’s existing line of liquid coatings and are engineered for architectural applications such as building panels, curtain walls and storefronts.
Made using Kynar 70-percent polyvinylidene fluoride (PVDF) resin technology, these 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 the company’s liquid coatings.
Powder coatings are formulated with color pigmentation that performs in virtually every type of climate. Also, the powder coatings are applied using a 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 protection, adhesion and colorfastness, even in extreme environments such as seacoast exposure, the company says.
These powder coatings are available exclusively through members of the PPG Certified Applicator Program, an elite group of commercial coating applicators certified by PPG to apply high-performance fluoropolymer coatings to aluminum architectural components.
