Market dynamics in containerised shipping are opening up fast-growing coating applications globally, especially for polyurethane (PUR) and polyurea (PUA) heavy duty corrosion protection coatings. Sea transport of goods in ISO standard containers forms a large and fast-growing business sector. Market opportunities for polyurethane and polyurea coatings are considered. Container ships are built in sections which are kept outside before final assembly and coating. Replacing the epoxy intermediate coat with polyurethane avoids problems of degradation during storage. High levels of protection against impact damage are needed on open hull top areas. Suitable coatings include a high-build 2K direct to metal solventfree PUR or a 2K polyurethane/epoxy hybrid. Single-pack PUR coatings are preferably used to protect sheet steel piles in harbour construction, as they can be applied at high humidities even to damp surfaces. A distinct market segment is emerging in the form of large dockside cranes forcontamerhandling. Suitable 2-coat systems are based on epoxy primers with aliphatic PUR topcoat.
