Extended 5,000-hour corrosion protection
Greenkote G5k™ is a significant advance in the company’s line of Greenkote® anti-corrosion metal coatings. The proprietary G5k delivers a minimum of 5,000 hours of corrosion protection for metals, verified by G5k being tested at ASTM Specification B117.
This ASTM specification is an established industry standard for accelerated testing of the corrosion resistance of metals and coated metals in a salt-spray corrosive environment over extended periods of time.
For extra-challenging anti-corrosion applications
The Greenkote name has become synonymous with advanced metal corrosion protection for a very broad range of needs. Now, G5k becomes the new high end in Greenkote high-performance coatings – with no red rust visible after 5,000 hours of standardized salt-spray testing at a recognized industry laboratory. 
This level of performance addresses the most challenging anti-corrosion applications, including those in marine and coastal environments as well as many automotive and industrial uses that expose metal parts to wetness or harsh chemicals for long periods of time. For these and many other types of challenging applications, G5k can extend service life and reduce maintenance and replacement costs significantly.
Extended protection plus all the standard Greenkote benefits
G5k also offers all the other performance benefits that Greenkote is known for. Because Greenkote coatings are actually diffused into the metal, they enable superior adhesion, longer life, and more conformal coverage, which allows their use on complex geometries such as small threaded parts. These coatings also provide an excellent surface for painting and rubber bonding.
Importantly, Greenkote also eliminates the introduction of hydrogen embrittlement, which is an intrinsic problem with many traditional anti-corrosion coatings. And the Greenkote coating process doesn’t use any hazardous chemicals or produce any toxic byproducts, so it is uniquely eco-friendly, RoHS compliant, and free of environmental regulations.
For these reasons, Greenkote coatings have been replacing many older anticorrosion processes such as electroplating, hot-dip, sherardizing, and metal flake. Greenkote coatings can be applied to a broad range of metal parts, from threaded fasteners to stamped and cast pieces, in sizes from 0.2 to 78 inches.
