PPG publishes new guide specification for coil and extrusion coatings

Date: 3 July 2008

PITTSBURGH, June 30, 2008 – PPG Industries’ (NYSE:PPG) industrial coatings business has published a new guide specification for its liquid and powder coil and extrusion coatings.

PPG is the first coatings company to make selection and specification of factory-applied architectural coatings easier by producing a guide formatted to the Construction Specifier Institute’s (CSI) Masterformat 2004.

“With the addition in August of Duranar powder coatings to our existing lines of Coraflon and Envirocron powder coatings, PPG will offer more choices for architectural metals than ever before,” said Henry Lowman, PPG director, extrusion products. “With a comprehensive collection of liquid and powder coatings, backed by an architectural support team, PPG is uniquely qualified to help specifiers select the best coating for their specific projects.”

The new PPG IdeaScapes Guide Specification covers protocols for shop- and factory-applied metal coatings, and the 10-page document is divided into three sections. The first details industry-specific testing and performance guidelines for metal coatings, as specified by the American Architectural Manufacturers Association (AAMA), American Society for Testing and Materials (ASTM) International, ENERGY STAR and LEED (Leadership in Energy and Environmental Design), among others. A second, more extensive section shows test data applicable to individual PPG coil and extrusion coatings, such as Duranar, Coraflon and Acrynar coatings. The final section covers installation requirements for shop-applied coatings.
