HI-AQU 8040 Waterborne Alkyd Coating is a waterborne coating. An environmentally friendly waterborne coating for use as a primer or primer-topcoat in one in the coating of new and maintained steel structures in moderate atmospheric environments. HI-AQU 8040 Waterborne Alkyd Coating is a one-component waterborne coating, free from irritating odour, with good anti-corrosion performance and application properties. 1.37 ± 0.1 kg/L (varies slightly with colour). Coating surfaces shall be clean, dry and free from contamination. Parameters on this page: volume solids 41 ± 3%, dry film thickness 30–60 µm, theoretical spreading rate 0.13 kg/m².

The surface to be coated shall be clean, dry and free from contamination. Surface assessment and cleaning shall follow ISO 8504. Oil and
Remove oil and grease in accordance with SSPC-SP1 solvent cleaning.
Abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 (SSPC-SP10 gives better results). If the blasted surface oxidises before application, it must be re-prepared to the specified standard. Surface defects exposed after blasting must be ground, filled or otherwise suitably treated. Surface roughness should be 40–75 µm.
Repair of damaged areas: damaged areas must be abrasive blast cleaned to Sa21/2 (ISO 8501-1:2007) or SSPC-SP6 (for optimum performance, blast clean to SSPC-SP10). Where abrasive blasting is not possible in local areas, mechanical grinding to St3 (ISO 8501-1:2007) is permitted. HI-AQU 8040 may be applied only after surface preparation. Before application of HI-AQU 8040 waterborne alkyd paint, ensure the surface to be coated is clean and dry, and application must be carried out within the specified recoat interval (refer to the relevant product application data).
Other surfaces: if the coating is to be applied to other substrates, consult the Protective Coatings Division of Nippon Paint Industrial Coatings.
Application is not recommended at ambient temperatures below 5 °C or above 50 °C, or relative humidity above 75%; steel
The temperature should be at least 3 °C above the dew point of the surrounding air.

Note: *the surface must be free of chalking and contamination before recoating. Prolonged outdoor exposure, a smooth surface or contamination adversely affects recoat adhesion; the surface must therefore be roughened, sweep blasted or high-pressure water jetted to ensure adequate adhesion.
The data above are for guidance only. Actual recoat and drying times may be shorter or longer depending on film thickness, ventilation, humidity, coating system, and prior hand or mechanical preparation conditions.
