PPG Repaints Historic Building in Philadelphia
The Bulletin Building recently underwent a series of transformations, including a new, galaxy red paint job by PPG. The company applied a Coraflon powder coating for the structure’s new signature feature, a multistory glass façade.
PPG recently contributed to a renovation of Philadelphia’s historic Bulletin Building. Designed in 1954 as the home to the Philadelphia Bulletin newspaper, the Bulletin Building has stood for decades as one of the iconic structures in the city. When the newspaper folded in 1982, the building underwent a series of transformations, and it now comprises a laboratory and retail space.
As part of the renovation, PPG partnered with Spectrum Metal Finishing, a member of the PPG Certified Applicator Program (CAP), to develop and apply a customized PPG Coraflon powder coating for the structure’s new signature feature, a multistory glass façade on the east elevation. With a glossy “galaxy red” PPG Coraflon powder coating formulated exclusively for the project, PPG says the Bulletin Building is now the main attraction in the city’s new Schuylkill Yards development.
PPG adapted its automotive coatings expertise to create a PPG Coraflon powder topcoat that incorporates “glass flake” technology to increase sparkle, depth and dimension in the coating’s sheen. The result is a deep, cherry-red coating that achieves 70-degree gloss while complying with the Fenestration and Glazing Industrial Alliance (FGIA) and American Architectural Manufacturers Association (AAMA) 2605 specification, which is said to be the industry’s highest weathering standard.
PPG says the pearlescent effect of the coating was heightened by Spectrum, which finished the aluminum framing using a two-bake paint application system. Powered by 12 computer-driven electrostatic guns, the two-coat system enabled PPG’s galaxy red base coat to cure on the metal substrate before it was top-coated with the high-gloss powder. By inserting a bake interval between the application of the base coat and the topcoat, Spectrum’s coating system prevented the glass flake in the topcoat from bleeding into the base coat, which further enhanced the finish’s three-dimensional effect.
PPG applied touch-ups during panel installation with PPG Coraflon ADS coatings in the same galaxy red color to ensure long-term color retention and chalk resistance. Coraflon ADS coatings are two-component coatings optimized for restoration of weathered architectural metals that offer a long-lasting, resilient finish.
Based on a proprietary fluoroethylene vinyl ether (FEVE) formulation, PPG Coraflon powder coatings are formulated to provide exceptional UV durability, colorfastness and gloss retention. With low volatile organic compound (VOC) content, Coraflon ADS coatings meet code requirements for most regions and can be applied on building panels, architectural accents, curtainwalls, roofs and more structurally sound surfaces.
Richard Maimon, lead architect for the project, says his firm reimagined the Bulletin Building, designed by renowned architect George Howe, to retain the scale, massing and character of the original structure while modernizing the design to accommodate new users and standards.
Maimon explains, “Our design restores and enhances the original fabric and features of the building while incorporating evolutionary interventions such as the red-framed glass façade and an alphabet-patterned frit, which pays homage to the building’s heritage.”
