Original Press Release:

New CLEARLOK® MAX Topcoat from Birchwood Casey Forms a Durable, Clear Coat on Tools and Similar Components

Eden Prairie, Minnesota: CLEARLOK® MAX Topcoat is another finishing first from
Birchwood Casey. New CLEARLOK MAX Topcoat is a water-based blend of acrylic polymers
that forms a scuff resistant clear coat finish on all metal surfaces.

What's unique about this finish is its densely packed polymer structure that forms a tightly adherent barrier against corrosion while enhancing the beauty and durability of the surface. With these properties, the finish serves as an ideal topcoat for black oxide or other surface coatings such as phosphates and antique finishes. It can also be applied directly to clean or shot-blasted metal surfaces such are bare steel, aluminum, nickel and zinc plating.

Supplied as a liquid concentrate, CLEARLOK MAX Topcoat is pH neutral and nonhazardous,
and is safe to apply without ventilation. The concentrate is diluted with water, applied to parts by immersion, then dried at 70-130° F, achieving a nominal film thickness of about .002 inches. Once dry to the touch, the parts are ready for assembly or packaging. Full hardness is achieved in about 24 hours.

Minimum humidity resistance is 400 hours (ASTM D1748), depending on film thickness.
For severe duty applications requiring extra corrosion resistance, the dried CLEARLOK MAX finish can be sealed with DRI TOUCH® Rust Inhibitor, to create an even more impervious barrier against humidity and corrosion.

Typical CLEARLOK MAX applications include all types of hand tools, machine
components, power transmission components, pumps, valves and oilfield equipment.
Available direct from Birchwood Casey in 5 and 55 gallon drums, CLEARLOK MAX
Topcoat may be ordered online for immediate shipment at
