Abstract

This invention describes a metallic article (2) coated with a radiation curable coating (10) that exhibits resistance to weathering and UV exposure. The radiation curable coating (10) is comprised of greater than about 95% solids by weight and is either clear or pigmented.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Applications 60 / 623,498, 60 / 623,689, 60 / 623,499, and 60 / 623,688, filed October 29, 2004, which are hereby incorporated by reference. field of invention [0003] The present invention generally relates to metals coated with liquid coating systems. In particular, the present invention relates to coated metals having applied thereto a radiation curable coating having greater than about 95% by weight solids. Background of the invention [0004] Coating solvents used in conventional coating operations often contain volatile organic compounds (VOCs), which evaporate from the solvent and act as harmful Air pollutants (HAPs) are released into the atmosphere. In addition, large amounts of hazardous waste are generated as a by-product of these coating operations. With increasing environmental concerns and increasingly stringent government regulations, there is an increased...
