Application
🔧 Construction Method
Airless spraying
Nozzle pressure: 14 MPa – 21 MPa
Nozzle hole diameter: 0.6mm – 0.8mm
If brush or roller application is used, more coats will be required to achieve the specified dry film thickness. Spray data is for reference only and may be adjusted. Pressure applies to material temperature at 20°C [68°F].
🛡️ Surface Treatment and Construction Conditions
Remove oil, grease and other contaminants with a suitable cleaning agent.
High-pressure water cleaning removes salt, detergents and other contaminants.
Remove dust, sand and loose materials.
To avoid condensation, please apply on a clean and dry surface with a temperature at least 3°C [5°F] above the dew point.
The relative humidity during construction and curing must be below 85%.

Frequently Asked Questions (FAQ)
Q
What makes acrylic topcoat suitable for outdoor and marine environments?
Acrylic topcoat features high weather resistance and excellent UV protection, which prevents color fading, coating aging, and degradation caused by prolonged sun exposure — making it ideal for ships and outdoor machinery used in harsh conditions.
Q
What application methods can be used for this topcoat?
The topcoat can be applied via airless spraying (recommended), brush, or roller. For spraying, use a nozzle pressure of 14–21 MPa and a nozzle hole diameter of 0.6–0.8mm. Note that brush or roller methods may require additional coats to reach the specified dry film thickness of 30μm.
Q
How long does the topcoat take to dry under different temperatures?
Drying time varies with temperature. At 10°C, dry-to-touch takes 30 minutes and actual drying takes 5 hours. At 20°C, it is 20 minutes and 4.5 hours respectively. At 30°C, dry-to-touch takes 15 minutes and full drying completes in 4 hours.
Q
What surface preparation is required before applying the topcoat?
The surface must be clean and dry. Remove all oil, grease, salt, and contaminants using a suitable cleaning agent and high-pressure water washing. Dust, sand, and loose materials should also be cleared. Ensure the surface temperature is at least 3°C above the dew point, and relative humidity is below 85% during application and curing.
Q
What is the shelf life and storage requirement for this product?
The product has a storage period of 12 months when stored at 25°C. It is recommended to store in a cool, dry place away from direct sunlight and extreme temperatures to maintain product quality.
Q
Is this topcoat available in multiple colors, and what gloss level does it offer?
Yes, this acrylic topcoat is available in various colors to meet different aesthetic requirements. It provides a high-gloss finish, which helps maintain a vibrant and long-lasting appearance on ship hulls and engineering machinery over extended periods.
