A speed dry coating for world´s longest hi-speed rail viaduct

The new Hi-Speed Rail link about to go into service between Tangier and Casablanca is a feat of engineering accomplished by a consortium of Moroccan and European firms, supplied by local Hempel teams and ACQPA certified in 4 different countries. 

The 350km line includes 286 new infrastructures and 13 viaducts, where Hempel participated in collaboration with our long-standing customers, Spain’s URSSA and Portugal’s Martifer, on what is already acclaimed as “the world’s longest rail viaduct.”

A contract requirement was that the 90,000m2 of steel surfaces be coated to an ACQPA-certified system, which in this case consisted of 2x100μm coats of Hempadur 47200, followed by 50μm of Hempathane Topcoat 55210.

The steel structures were shop-coated in Europe with Hempadur 47200, our two-component, epoxy that forms a tough and hard-wearing coating in extremely short drying times, making it ideal as a primer or intermediate coat for in-shop applications.
