Polyurethane Coatings


COROPUR polyurethane coatings for water immersed steel structures

In general, COROPUR for hydraulic steel applications is applied in at least 3 layers, each of around 150 – 250 µm dry layer thickness. For corrosion protection of hydraulic steel parts in accordance with EN ISO 12944-5 requirements (corrosivity categories lm1, lm2 and lm3 with fresh water, seawater and soil), COROPUR TAR, COROPUR TAR 21,

COROPUR TF 21 and COROPUR NON ABRASIV, in combination with suitable primers, are mainly used.
