Abstract
This invention provides a masking material that can be used to protect an underling surface (e.g. an automobile surface) during an overcoating (e.g. painting) operation. The masking material in one embodiment includes a thickener and a pH control agent and water. The masking material can be applied to a surface that is to be protected from paint overspray or other coating processes, allowed to dry, and the surface then coated (e.g. with paint). After drying of the paint, or other coating, the masking material can removed by water washing.
Claims25
A masking composition for the temporary protection of a surface during a coating procedure, said masking composition comprising an aqueous solution of:
- a polyvinyl alcohol film former present in an amount ranging from about 0.15 weight percent to about 25 weight percent of said masking composition;
- a siloxane-based surfactant in a concentration sufficient to allow said masking composition to wet a painted surface of an automobile;
- and
- an ethoxylated alcohol surfactant;
- wherein said masking composition has a shelf life at room temperature greater than about 1 year.
