US 6,335,078 B2 · Curable masking material for protecting a passage hole in a substrate

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.
