PROTECTIVE COATING SYSTEMS FOR PAINT BOOTHS THAT RESIST DISCOLORATION

摘要

In various embodiments a protective coating composition for the temporary protection of a paint spray booth are provided where the compositions comprise an aqueous liquid that when applied to a surface of said paint booth dries to form a peelable white film thereon, where said liquid coating comprises a liquid film former that when applied to a surface and dried forms a peelable film where said liquid film former comprises a polyvinylbutyral (PVB); and a pigment where the pigment comprises a sulfate process rutile titanium dioxide; and where protective coating composition is more resistant to yellowing than the same composition when formulated with a chloride process titanium dioxide.
