PROTECTIVE COATINGS INCLUDING PARTIALLY HALOGENATED MATERIALS AND METHODS FOR FORMING AND USING SAME

摘要

Protective coatings and methods for applying the same are described. A protective coating may be formed on a substrate to reduce or eliminate corrosion or other damage to the substrate. The protective coating may include at least one primer layer applied onto the substrate. The at least one primer layer may include polyphenylene sulfide. The at least one primer layer may be formed from polyphenylene sulfide and a partially halogenated material. At least one intermediate layer may be applied onto the at least one primer layer. The intermediate layer may include polyphenylene sulfide and a partially halogenated material. At least one top layer may be applied onto the at least one intermediate layer. The at least one top layer may consist essentially of a partially halogenated material. The at least one top layer may include polyphenylene sulfide and a partially halogenated material.

1. A method of coating a substrate to protect a surface thereof, the method comprising:
coating the surface with at least one primer layer comprising about 0% by weight to about 20% by weight of a first partially halogenated material and about 80% by weight to about 100% by weight of polyphenylene sulfide; coating the at least one primer layer with at least one intermediate layer comprising about 60% by weight to about 80% by weight of a second partially halogenated material and about 20% by weight to about 40% by weight of polyphenylene sulfide; and coating the at least one intermediate layer with at least one top layer comprising about 80% by weight to about 100% by weight of a third partially halogenated material and about 0% by weight to about 20% by weight of polyphenylene sulfide.
