PU Coating Systems

COROPUR stands for moisture-hardening, single component coating systems that can be applied by brushing, rolling or spraying procedures. Alongside the simplicity of application and their high tolerance to moisture, COROPUR coatings feature a combination of great surface strength with high elasticity, and so ensure long term corrosion protection of steel component parts. COROPUR is normally applied at least as a three-layer coating (DFT 150-250 μm per layer). COROPUR Tar, COROPUR Tar 21, COROPUR TF 21 and COROPUR Non Abrasive are mainly used for the corrosion protection of steel water engineering constructions according to the requirements of DIN EN ISO 129-44-5 (corrosivity category Im1, Im2 and Im3 for direct contact with freshwater, seawater and soil) in combination with the appropriate primers.
