Clear paint booth coating composition and method |
摘要 |
A crystal clear paint spray booth barrier coating comprising an aqueous solution of polyvinyl alcohol is disclosed. The polyvinyl alcohol may include a foam depressor for spray application of said coating. Fluorocarbon and non-ionic surfactants are disclosed for providing a smooth coating surface and improving the transparency of said coating. A polyacrylate thickener may be included to facilitate applying the coating to vertical surfaces. Methylparaben is disclosed for preventing the formation of mold on said coating and improving shelf life of the coating. The method disclosed includes mixing an aqueous solution of polyvinyl alcohol, at least one surfactant and a foam depressor, applying said mixture to the surfaces of the paint spray booth to be protected and equipment located in the paint spray booth, and allowing the coating to dry to a crystal clear coating. Methods of removing the coating include peeling the coating off as a film and water washing the coating.
