WATER-BASED METAL SEALANTS

Birchwood Technologies (Eden Prairie, MN) is offering two all-purpose Clearlok water-based sealants formulated to provide a protective topcoat on most metal surfaces. Clearlok is available in two forms: Clearlok Clear Urethane Sealant for super hard finishes, and Clearlok Max for faster drying and easier removal in alkaline soak cleaners.

Clearlok Clear Urethane Sealant is a heavy-duty, urethane polymer sealant that forms a hard, glossy protective coating. It works well on black oxide finishes on iron and steel, black finishes on aluminum, and on non-finished iron, steel and aluminum surfaces. This sealant can be used to enhance the gloss and overall appearance of the final finish. Clearlok polymer sealant is intended to add a quality look and feel to hand tools, automotive components, and machined components. The final protective coating thickness is 0.0001 to .00003 in.

It is rated for corrosion resistance of 24 hours of neutral salt spray or two hundred hours of humidity exposure.

Clearlok Max is a water emulsion blend of acrylic polymers and rust inhibitors that forms a clear protective coating. This finish serves as a topcoat for black oxide or other surface coatings.

It can also be applied directly to clean or shot-blasted metal surfaces such as bare steel, aluminum, nickel and zinc plating. This sealant is suited for use on hand tools, machine components, power transmission components, pumps, valves and oilfield equipment.

Once dry to the touch, the parts are ready for assembly or packaging. The final protective coating thickness is about .002 in. It is rated for corrosion resistance of 24 hours of neutral salt spray or two hundred hours of humidity exposure.

Both Clearlok and Clearlok Max sealants are supplied as liquid concentrates that can be diluted with water for application using immersion tank processes, spray application, or easy brush-on application. They are easily implemented on most plating and finishing lines.

Both products are non-toxic, fume-free and safe to use in any process line without ventilation. They are available in five and 55-gal. drums.
