Greenkote coatings serve a broad spectrum of industries and applications

Patented Greenkote® anti-corrosion coatings improve the performance of many different metals, alloys and sintered materials, most importantly increasing their resistance to corrosion and wear. This is why Greenkote is particularly useful for protecting fasteners, fittings, castings, stampings and numerous other metal parts that are exposed to weather and corrosive environments at low and high temperatures. Greenkote can also maintain uniform thickness and critical tolerances for parts with complicated geometries, and with its enhanced adhesion qualities it’s a natural base for duplex coatings. Thus, Greenkote finds a wide range of uses in industries such as…

• Construction        • Automotive        • Oil & Gas        • Mining        • Aerospace

• Rail        • Utilities        • Bridges        • Wind        • Solar        • Military        • Marine

For example, in the auto industry…

The Greenkote product line gives automotive manufacturers and Tier-1 and -2 suppliers a host of options. Greenkote can provide very uniform anti-corrosion coatings for small and precision parts with complex shapes. It also creates a very effective base coat for paints, sealers, e-coat and other topcoats. For example, powder metal or metal injection molded (MIM) components can be processed with no sealer or other special treatment. In addition, Greenkote provides exceptional adhesion for steel parts bonded to natural and synthetic elastomers and plastics. And the coating’s low-friction properties can improve performance in such applications as the motion control of exterior rear view mirrors. Typical Greenkote automotive applications:

  • Fasteners, body hardware, door closure and lock parts
  • Exhaust, suspension, and engine components
  • Clamps and hose connections
  • Steel inserts for rubber and polyurethane moldings


Notably, Greenkote is one of the few anti-corrosion coatings that meets all of the auto industry’s strict environmental standards and regulations around the globe. Our coatings are in full compliance with the EU End of Life Vehicles (ELV) Directive (2000/53/EC). Greenkote has also won approval from the British Board of Agreement (BBA) under the Highway Authorities Product Approval Scheme (HAPAS). In addition, it is tested in compliance with the standards of the American Society for Testing & Materials (ASTM) and the Society of Automotive Engineers (SAE).

For example: in the construction industry…

Greenkote provides weather and corrosion resistant coatings for long-term protection, especially for parts that receive heavy exposure to the elements. Extensive salt spray testing has proven that these coatings meet extreme durability standards for a range of temperatures and environments.

Thus, a multitude of Greenkote coated bolts and fasteners are already being used in major construction sites all around the world — for many good reasons…

  • High quality corrosion protection up to 600°C
  • Salt spray resistance tested up to 1,200 hours, which can be increased further with sealers and topcoats
  • No hydrogen embrittlement
  • Hardness up to HV 550
  • Available thickness range of 5 to 100 µm
  • Resistance to damage from crimping and forming
  • Suitable for threaded bolts and nuts – no cleaning or re-tapping required after coating

Greenkote — widely approved, in use worldwide

Greenkote meets major international construction standards and has received numerous technical approvals. It is approved by the American Society for Testing and Materials (ASTM) and is fully compliant with ASTM A1059/A1059M, an industry-standard specification for zinc alloy coatings. In addition, Greenkote is recommended by the UK Steel Construction Institute for tension-control bolts. It is also approved by the British Highway Agency and the German Institute of Construction (DIBt).

Some of the major-name users of Greenkote anti-corrosion coatings include Audi, Bosch, Daimler AG, Ford, GE, General Motors, Iscar, Motorola, Volkswagen, Whirlpool and the Israeli Defense Forces (IDF). Through Greenkote’s licensee Tension Control Bolts Ltd., the TCB/Greenkote product has been specified for use on many major heavy construction projects, such as London’s Oval Cricket Ground Stadium, Wembley Stadium Bridge, Heathrow Airport Terminal 5 and numerous others.
