PPG Industries coil and building products coatings group will highlight CORAFLON GR (graffiti-resistant) and DURANAR GR coatings at the 2014 American Institute of Architects (AIA) National Convention and Expo in Chicago, June 26-28. Coraflon GR high-gloss and Duranar GR medium- and low-gloss coatings are made with a proprietary formula that provides a clear, graffiti-resistant barrier over the pigmented color layer of the coating, enabling surfaces to be wiped clean from graffiti, paint overspray, pen and marker ink, lipstick, scuff marks, tape residue, tar bugs and many other substances after application of DURAPREP Prep 400 graffiti remover by PPG. The graffiti system developed by PPG is believed to be the only one sold and tested by the same company.
