Polymer Sealant for Metal Surfaces


Clearlok is a water-based polyurethane sealant formulated to provide a protective topcoat on most metal surfaces. It produces a clear, hard and glossy coating that is non-polluting and contains no harmful VOC content. It reportedly works well on black oxide finishes on iron and steel, black finishes on aluminum, and on non-finished iron, steel and aluminum surfaces. The final protective coating thickness is 0.002–0.008 mm. It is rated for corrosion resistance of 12–24 hours of neutral salt spray or over 100 hours of humidity exposure. With no VOC content, the water-based formula helps manufacturers and platers meet current EPA restrictions and automotive “end-of-life” directives without compromising coating performance. Because it works well on most metal surfaces, it can be used to enhance the gloss and overall appearance of the final finish.
