Curable masking material for protecting a passage hole in a substrate
First Claim
Patent Images
1. A curable masking material in a metal-based substrate comprising:
- a resin that does not serve as a adhesion site for any coating which is subsequently applied and at least one rheology-modifying additive;
a substrate with a passage hole, and a coating on the substrate;
said resin being in the form of a protrusion, which fills the passage hole and extends above the surface of the substrate by at least about 50% greater than the thickness of the coating.

Abstract
A curable masking material for protecting a passage hole in a metal-based substrate is formed of an extrudable resin composition. The resin composition is thermally stable at elevated temperatures, and does not serve as an adhesion site for any coatings which are applied over the masking material. In addition, the resin composition has non-Newtonian flow characteristics and is adapted to form a protrusion extending from the passage hole upon extrusion to fill the passage hole.
