Graffiti-resistant barriers, related compositions and methods24m

摘要

A composition useful for preparation of a graffiti-resistant barrier coating, related methods and compositions. The composition comprises from about 0.1 to about 30 percent by weight polyvinyl alcohol of molecular weight from about 7,000 to about 120,000 and being at least about 50% hydrolyzed; from about 0.1 to about 30 percent by weight non-stick agent such as silicone or polytetrafluoroethylene; and from about 0.1 to about 40 percent by weight adhesion promoter such as a urethane composition.
