描述
Physical Parameters

Gloss: Matt / Flat, Semi-gloss (semi-gloss can be selected for the atmospheric zone; flat is preferred for the tidal and full immersion zones)
Standard Film Thickness:
Wet Film Thickness (WFT): 200 μm
Dry Film Thickness (DFT): 80 μm
Theoretical Spreading Rate: Approx. 4.7 ㎡/kg

Application Instructions
Mixing Ratio: Base : Curing Agent = 8 : 1 (by weight)
Pot Life (23°C): 2 hours
Thinner: Offshore Platform Anti-Corrosive Paint Dedicated Thinner (Note: The use of general thinners is strictly prohibited as it will compromise the film’s anti-corrosive properties and weatherability.)
Cleaning Solvent: Offshore Platform Anti-Corrosive Paint Dedicated Thinner. Clean all tools immediately after use to completely remove residual paint, preventing tool blockages and cleanup difficulties caused by product curing.
Application Methods: Airless Spray, Conventional Air Spray, or Brush/Roller Coating.

Surface Preparation
The surface of the substrate or intermediate coat must be clean, dry, and completely free of oil stains, corrosion, old paint residue, marine growth, and salts.
Surface cleanliness should reach Sa2.5 grade (abrasive blasting) or St3 grade (manual/power-tool cleaning). Remove surface salts, dirt, and dust using high-pressure fresh water (or rinse with seawater first, followed by a thorough fresh water wash). Allow the surface to dry completely (moisture content $\le$ 6%) before application.
When overcoating existing offshore platform anti-corrosive paint or epoxy coatings, the old film must be abraded and roughened to eliminate chalked, loose, or peeling areas, ensuring excellent intercoat adhesion and preventing delamination.
Application Conditions
Temperature & Humidity: The application temperature range is -5 ~ 40°C with a relative humidity (RH) below 85%. The substrate surface temperature must be at least 3°C above the dew point. All measurements of temperature, humidity, and wind speed must be taken close to the substrate in the actual work area.
Wind Constraints: High-altitude spray application is not recommended if the wind speed exceeds Force 5 ($> 8.0 \sim 10.7\,\text{m/s}$).
High-Temperature Constraints: Coating operations are not recommended if the substrate surface temperature exceeds 50°C, avoiding film defects like pinholes, wrinkling, or incomplete curing.
Adverse Weather: Outdoor application is strictly prohibited during rain, snow, heavy winds, sandstorms, dense fog, high humidity, or immediately before a rainstorm.
Sub-Zero Operations: For applications below 0°C, the substrate surface must be entirely free of ice, snow, or frost, and anti-freezing measures must be taken to guarantee normal film formation.
Coating System Compatibility
Preceding Coats: SH-E1501 Zinc-Rich Epoxy Primer or SH-E1502 Epoxy MIO Intermediate Paint.
System Recommendation: For the splash zone and full immersion zone, pairing with a specialized offshore platform anti-corrosive intermediate paint is recommended to maximize performance. For the atmospheric zone, this product can be directly matched as the topcoat. Using these in combination creates a complete, long-term marine heavy-duty anti-corrosive system.
Packaging Specifications
Base (Part A): 24 kg
Curing Agent (Part B): 3 kg
Storage
Store this product in a cool, dry, and well-ventilated indoor warehouse, away from open flames and heat sources. Avoid direct sunlight.
Do not store together with acidic or alkaline substances. The shelf life is 12 months under normal room temperature (5-30°C) conditions.
The base and curing agent must be stored separately. Once opened, the product should be used as soon as possible; any unused portion must be tightly sealed and stored.
Safety Precautions
All sources of ignition and smoking are strictly prohibited at the mixing and application sites. Maintain excellent ventilation to reduce paint mist concentration and avoid the inhalation of harmful components (especially in high-altitude application environments where ventilation protection must be reinforced).
Applicators must wear appropriate personal protective equipment (PPE), including protective masks, safety goggles, solvent-resistant gloves, and anti-slip shoes. Safety harnesses are mandatory for high-altitude operations to prevent falls, paint mist inhalation, or eye and skin contact.
If paint contacts the skin, wash immediately with soap and water or a specialized skin cleanser. If it splashes into the eyes, rinse continuously with plenty of water for at least 15 minutes and seek immediate medical attention.
Warning signs must be placed around the application area to restrict unauthorized entry. Clean up and collect residual coatings and thinners promptly after construction for centralized disposal to avoid polluting the marine and surrounding environments.
Disclaimer
The protective performance of any coating largely depends on application factors. Surface preparation and film thickness will directly affect the service life of the coating. Users must ensure compliance with the specified application conditions.
