What Greenkote does

Greenkote is a privately held UK-registered developer and licensor of patented thermal diffusion metal coatings, with operational headquarters and a major coating facility in Brook Park, Ohio. The company's core technology — Thermo-Chemical Surface Modification (TCSM) — is a dry, acid-free batch process that diffuses zinc, aluminum, and proprietary ingredients into metal substrates at elevated temperatures, forming a metallurgical bond that eliminates hydrogen embrittlement, withstands corrosion up to 600°C, and uses roughly 90% less powder than competing diffusion coatings. The product portfolio includes the PM-1 (15–100 µm), PM-10 and PM-21 (5–15 µm) base coatings, the G5k advanced coating delivering 5,000+ hours of ASTM B117 salt spray protection, and duplex systems combining Greenkote basecoats with e-coat or powder topcoats.

Greenkote monetizes through three primary streams: (1) direct contract coating services at its Ohio headquarters and at the wholly-owned Greenkote IPC facility in Queretaro, Mexico, which also offers e-coating and powder coating; (2) sale of turnkey Greenkote Systems equipment (50kg to 4,000kg batch sizes) to independent licensees; and (3) recurring supply of proprietary powder formulations to those licensees. The licensee model extends the company's reach into the UK (Tension Control Bolts, Anochrome), Italy (Elettroplast), China (Shanghai Premier), and South Africa (Duraset), with direct sales offices in London and Hong Kong. Customers include qualified programs at Volkswagen, Audi, Daimler, Ford, GM, Bosch, GE, Whirlpool, and projects spanning nuclear (Chernobyl New Safe Confinement, UK coastal plants), oil and gas (Amur Gas Processing Plant), construction (Leadenhall, Wembley, Heathrow T5), and rail (NARSTCO). The company is certified to ISO 9001, ISO/TS, ISO 14001, RoHS, and EU ELV Directive standards.

Core offering

Greenkote develops and applies a patented thermal diffusion zinc-based metal coating technology (Thermo-Chemical Surface Modification, TCSM) that diffuses zinc, aluminum, and proprietary ingredients into metal substrate surfaces to deliver high-performance, eco-friendly corrosion protection. The company offers its own line of coating products (PM-1, PM-10, PM-21, G5k), operates direct coating facilities, and licenses turnkey equipment systems and proprietary powder formulations to independent coating operators worldwide.

Product overview

Greenkote offers a comprehensive portfolio of thermal diffusion metal coating products and related services centered on its patented zinc-based Thermo-Chemical Surface Modification (TCSM) process. The core product line includes PM-1 (15–100 µm thick coatings for heavy-duty corrosion protection), PM-10 (5–15 µm zinc-aluminum for stamped parts), and PM-21 (5–15 µm zinc-aluminum-magnesium for fasteners), all providing metallurgical diffusion bonding, hydrogen embrittlement elimination, and eco-friendly processing. The flagship G5k advanced coating delivers 5,000+ hours of ASTM B117 salt spray protection for extreme environments. Greenkote IPC provides industrial-scale e-coating and powder coating services from a dedicated facility in Mexico. Greenkote Systems offers licensed turnkey coating equipment for in-house deployment. Duplex coating systems combine Greenkote basecoats with topcoats to address specialized performance, appearance, or color requirements across automotive, construction, rail, oil & gas, and other industries.
