Abstract
Abstract An aqueous composition which produces a clear, protective coating on a wide variety of surfaces, consisting essentially of a suspension of vinylidene polymers, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, a halogenated polysilane surfactant, sodium benzoate rust proofer, defoamer (mineral oil in ethylene glycol monobutyl ether), and water. A cleaning and priming composition is also provided, for removal of graffiti and the protective coating. The latter comprises preferably ethylene glycol monoethyl ether, methylene chloride, nonylphenol ethoxylate, triethanolamine, and water.
