Application
Construction Method
Airless spraying
Nozzle pressure: 14 MPa – 21 MPa
Nozzle hole diameter: 0.6 mm – 0.8 mm
If applying by brush or roller, additional coats will be required to achieve the specified dry film thickness. Spray data is for reference only and may be adjusted.
Pressure is applicable at a material temperature of 20°C [68°F].
Brush and roller application is only suitable for line marking and small repair areas.
Construction Conditions
During application and curing, the substrate surface temperature must be above 5°C [41°F].
To avoid condensation, the substrate temperature during application must be at least 3°C [5°F] above the dew point, clean and dry.
Relative humidity during the construction and curing process must be less than 85%.
Surface Treatment
Remove oil, grease and other contaminants with a suitable cleaning agent.
High-pressure water cleaning removes salt, detergents and other contaminants.
Surface blasted to Sa 2½ (ISO 8501-1) / SP 10 (SSPC).
Small areas can be cleaned by hand or with power tools as an alternative to sandblasting.
Flash rust should not exceed FR L (ISO 8501-4).
The substrate surface should be Medium (G) (ISO 8503-2).

Frequently Asked Questions (FAQ)
What is this paint primarily used for?
This paint is designed as an anti-corrosion primer for both new shipbuilding and old ship maintenance. It provides strong corrosion resistance to seawater and offers cathodic protection.
Can this paint be applied in cold or humid conditions?
Yes. The paint can be applied at low temperatures (substrate surface must be above 5°C [41°F]) and is capable of curing in humid environments, provided relative humidity remains below 85%.
What is the recommended application method?
Airless spraying is the recommended method, with a nozzle pressure of 14–21 MPa and a nozzle hole diameter of 0.6–0.8 mm. Brush and roller application is suitable only for line marking and small repair areas, and additional coats may be required to reach the specified dry film thickness.
What surface preparation is required before applying the paint?
The surface should be blasted to Sa 2½ (ISO 8501-1) / SP 10 (SSPC). Oil, grease, salt, and other contaminants must be removed. Flash rust should not exceed FR L (ISO 8501-4), and the substrate profile should be Medium (G) per ISO 8503-2.
What is the mixing ratio and pot life of this product?
The mixing ratio is Base : Hardener at 2.5 : 1 by volume. The pot life varies by temperature — approximately 12 hours at 10°C, 8 hours at 20°C, and 6 hours at 30°C.
How long can this product be stored, and under what conditions?
The storage period is 24 months when stored at 25°C. Ensure the product is kept in a cool, dry environment and sealed properly to maintain its performance characteristics throughout its shelf life.
