we've known for years about the change in VOC classification from having a dedicated category of Intumescent Coatings to considering them as an Anti-Corrosive coating. A current LEED-HC project has RectorSeal's "Biostop Putty" and "BioStop Wrap Strip". Common sense tells me that the Biostop Putty (which seals holes in fire-rated walls) is a Sealant; while the Wrap Strip (a tape that wraps around a pipe) is a coating, but I've learned to not simply trust common sense. Any enlightened input is greatly appreciated. Thank you, Andrew
