Abstract
The invention provides a coated metal substrate comprising a metal substrate having an outer surface, a maskant film adhered to at least a portion of the outer surface of the metal substrate, the maskant film having a pattern of scribed lines therein, and a line sealant composition applied to the scribed lines in a maskant film. Both the maskant film and the line sealant composition are preferably radiation cured and substantially solvent-free. The invention also provides a method of protecting a metal substrate from chemical exposure by utilizing the radiation-cured maskant film and line sealant composition.
Claims42
A coated metal substrate, comprising
- a metal substrate having an outer surface;
- a maskant film adhered to at least a portion of the outer surface of said metal substrate, the maskant film having a pattern of scribed lines therein;
- and
- a radiation-cured and substantially solvent-free line sealant overlying said scribed lines in said maskant film.
A coated metal substrate, comprising
- a metal substrate having an outer surface;
- a radiation-cured and substantially solvent-free maskant film adhered to at least a portion of the outer surface of said metal substrate.
A coated airplane fuselage panel, comprising:
- a metal airplane fuselage panel having an outer surface;
- a radiation-cured and substantially solvent-free maskant film adhered to at least a portion of the outer surface of said fuselage panel, said maskant film having a pattern of scribed lines therein;
- and
- a radiation-cured and substantially solvent-free line sealant overlying said scribed lines in said maskant film, wherein said maskant film and said line sealant exhibit chemical resistance to a chemical treatment selected from the group consisting of chemical milling, anodizing, and deoxidizing.
