  • Methods for protecting substrates from graffiti and for removing graffiti
    Patent number: 6974605
    Abstract: A system for protecting surfaces and facilitating the removal of unwanted substances therefrom is disclosed, the system including a polymeric coating having a low volatile organics content (VOC) which is safe for the environment, and a cleaner for application to the coating to remove material from the coating, such as graffiti. The coating may be either a water-based epoxy comprising a bisphenol A resin and polyamide resin, or an aliphatic urethane comprising a polymer having reactive sites which react with a isocyanate and an aliphatic isocyanate. The cleaner is suitable for removing all manner of epoxy and urethane based spray paints, indelible inks, industrial chemicals, and the like. The cleaner comprises N-methyl pyrrolidone in a concentration of fifty percent by weight or greater and a surfactant.
