Hempel Unveils HEMPADUR 4774D Coating for Wind Turbine Towers

Hempel has launched a new combined primer and mid-coat designed specifically for wind towers. The new coating, HEMPADUR 4774D, will be used in Hempel’s well-known two-coat anti-corrosive system for wind turbine towers to address previous UV stability issues.

Hempel’s two-coat wind tower protection system dries up to 30% faster than equivalent three-coat systems, helping to eliminate production bottlenecks, increase throughput and reduce drying hall costs.

Since it was first launched in 2008, the system has effectively become the industry standard within two-coat paint systems for wind towers, and around 70 per cent of producers using a two-coat system for wind towers choose Hempel.


Developed specifically for wind towers, HEMPADUR 4774D will replace the combined primer and mid-coat currently used in Hempel’s two-coat system and will improve the system by addressing previous UV stability issues.


Hempel is one of the leading coatings suppliers to the wind energy sector and supplies coatings to more than 50% of all wind turbines, towers and blades produced around the world.
