Birchwood Technologies’ Clearlock all-purpose water-based polyurethane sealant provides a protective topcoat on most metal surfaces. The coating provides scratch and scuff resistance as well as long-term corrosion protection. It produces a clear, hard and glossy coating that is non-polluting and contains no VOC content, the company says.
The polymer sealant is a heavy-bodied liquid that can be diluted with water for immersion tank processes or for easy brush-on application. According to the company, the coating can dry quickly at room temperature or can be force-dried using warm air. The final protective coating thickness is 0.0001" to 0.0003", and is rated for corrosion resistance of 12 to 24 hr. of neutral salt spray or more than 100 hr. of humidity exposure. It is well-suited for use on black oxide finishes on iron and steel, black finishes on aluminum, and non-finished iron, steel and aluminum surfaces.
