Corrosion resistant barrier consisting of a UV light cured anti-corrosive basecoat and thermoplastic topcoat

摘要

A protective surface, and the article protected is described in which the surface is formed as a UV initiated basecoat over which a thermoplastic top coat is applied. The surface is first cleaned, then the UV initiated basecoat applied as a liquid to a thickness of 2 to 25 mils. UV light initiates polymerization and then the topcoat of a thermoplastic formulation is applied, preferably by flame spraying. The protective surface is particularly useful on pipeline joints.
