PPG Industries’  industrial coatings business has introduced DURANAR® GR (graffiti-resistant) and CORAFLON® GR coatings. Duranar GR and Coraflon GR coatings feature a clear, graffiti-resistant barrier over the pigmented color layer of the coating. If the coating is spray-painted or otherwise marred, it can be cleaned by applying DURAPREP® Prep 400 graffiti remover by PPG. After the solution has been allowed to dwell on the stain for 10 to 60 seconds, it can be wiped with a clean cloth or scrubbed with a nylon brush. Most stains can be removed in 10 minutes or less. When applied on either Duranar GR or Coraflon GR clear coatings, Duraprep Prep 400 field-applied graffiti remover eradicates graffiti as well as paint overspray, pen and marker ink, lipstick, scuff marks, tape residue, bugs, tar and many other substances that mar the appearance of commercial buildings. It is believed to be the only graffiti-resistant coating system sold and tested by the same company. Scott Moffatt, PPG director, marketing, coil and extrusion coatings, said Duranar GR and Coraflon GR clear coatings were developed to help U.S. building owners combat a problem that costs an estimated $25 billion per year. “Building owners and architects are already very familiar with Duranar and Coraflon coatings because of their extensive color libraries and long history of durability,” he said. “The added ability to use these coatings as part of a graffiti-resistant system will make them even more valuable and versatile.”
