Incheon Steel is one of the largest steel manufacturers in Asia and produces over 8 million tons of steel annually. When one of its 90-ton furnace ducts needed an internal and external coating to stand up to heat, moisture and a heavy industrial macroenvironment they looked to POR-15 to provide a solution.

Introduction to POR-15®

POR-15® is a high performance, versatile aromatic moisture cured polyurethane coating designed for application directly on rusted or seasoned metal surfaces and concrete. It dries to a rock-hard, non-porous finish that does not chip, crack, or peel. Because POR-15® is non-porous, it is an excellent sealer for porous substrates and it completely protects from water, chemicals, salt, and mineral oils. The highly porous characteristics of most substrates and traditional coatings permit harmful elements to penetrate which initiates deterioration. POR-15® is the only coating that is able to protect and extend a surface or structures life expectancy due to its unique non-porous molecular composition. POR-15® is also able to withstand prolonged exposure to temperatures up to 600 degrees Fahrenheit.

POR-15® Preparation & Coating System 


Surface was cleaned and degreased with Marine Clean T to remove surface contaminants that interfere with duct coating and restoration.


Surface was prepared with Metal-Ready T to neutralize rust and corrosion with zinc phosphate and promote chemical bonding of POR-15®.
