ZD2190 Offshore Heavy-duty Anticorrosive Coating
Offshore heavy-duty anticorrosive coating is a high-solids, low-VOC two-component high-build epoxy barrier coating that provides long-term protection with a single coat. Grades containing glass flake in the film provide improved anticorrosion protection.
Excellent adhesion, corrosion resistance and cathodic disbondment resistance;
Excellent abrasion resistance;
Excellent water immersion resistance; good chemical resistance
Excellent mechanical properties
For the protection of steel structures in severely corrosive environments, such as the underwater areas of offshore structures, pile structures, external wall protection of buried pipelines, storage tanks, and steel structures in chemical plants, paper mills and similar environments. With suitable anti-slip aggregate added, it can serve as an anti-slip deck coating system. A single coat can reach a dry film thickness above 1000 µm, greatly simplifying the application procedure.

All surfaces to be coated must be clean, dry and free from contaminants. Before paint application, all surfaces shall be assessed and prepared in accordance with ISO
| 8504 | 2000. Oil and grease shall be removed in accordance with SSPC-SP1 solvent cleaning. |
|---|
The product shall be applied to surfaces abrasive blast cleaned to Sa2.5 (ISO 8501-1:2007) or SSPC-SP10. An angular surface profile of 40–70 µm (2–3 mil) is recommended. Surface defects exposed by blasting shall be ground, filled or otherwise treated in a suitable manner.
Approved primer must be clean, dry and free from soluble salts and any other surface contaminants. Unapproved primer shall be removed completely by abrasive blast cleaning to Sa2.5 (ISO 8501-1:2007).
| Aged coating | Suitable for application over certain firmly adhering, intact aged coatings; small-area testing and evaluation are required before application. |
|---|---|
| Others | Consult East China ZINDN Company. |
Substrate surface temperature must always remain at least 3°C above the dew point. Application in enclosed spaces requires adequate ventilation to ensure proper coating drying. During application and drying, avoid curing of the film under high humidity to prevent the formation of amine salts. Condensation during or immediately after application will cause a flat surface and a poor-quality film. Premature exposure to standing water will cause colour change.
Mixing: stir Component A (Base) separately until uniform, then stir Component A and Component B thoroughly until homogeneous, and add the appropriate amount of the recommended thinner to adjust to a suitable application viscosity. Once mixed, the product must be used within the specified pot life.

Note: the above data were measured under good ventilation, with reference to a 600 µm wet film and 75% relative humidity; thicker films extend the drying time. Actual drying time and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, early handling requirements and mechanical strength.

The offshore heavy-duty coating, like all epoxy paints, will chalk and fade on exposure to the atmosphere. This phenomenon does not affect corrosion protection performance.
The offshore heavy-duty coating can be applied at 1000–1200 µm in a single coat without affecting adhesion, corrosion protection performance or other properties. It simplifies the application procedure and improves coating efficiency.
Modified with the addition of anti-slip aggregate, the product can be used as an anti-slip deck coating system and shall then be applied over a suitably primed surface. Typical thickness is between 500 and 1000 µm. Apply with a suitable large-nozzle spray gun (air spray gun with a 5–10 mm nozzle). Small areas may be applied by trowel or roller. Consult East China ZINDN Company for details.
The offshore heavy-duty coating may be applied directly to prepared steel surfaces,
| Recommended primer: | Epoxy zinc-rich, epoxy zinc phosphate; |
