July 2003


Samsung is the largest business group in South Korea and is the worlds largest manufacturer of dynamic random memory and other memory chips. When multiple coating systems failed to protect its capital intensive wastewater treatment facilities, Samsung looked to POR-15, Inc. affiliate Jinsung Chemical & Ceramics to provide a non-porous 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 500 degrees Fahrenheit.

POR-15® Preparation & Coating System 


Surface was cleaned and degreased with Marine CleanT to remove contaminants that interfere with adhesion and restoration.


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