Coating hazards GB 30981.2-S-Pb≤1000-NC; complies with GB 30981.2-2025. This product contains no organotin compounds acting as biocides and complies with the international treaty adopted by the IMO in October 2001 on the control of harmful antifouling systems on ships (IMO document AFS/CONF/26).
For the paint system best suited to the surface to be protected, consult your local International Paint representative.
Applied in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated must be clean, dry and free of contaminants.
Wash with high-pressure or ordinary fresh water as appropriate, and remove all oil, grease, soluble contaminants and other foreign matter in accordance with the SSPC-SP1 solvent cleaning standard.
Newbuilding: Intersmooth 7476Si SPC must always be applied over the recommended primer. The primer surface must be dry and free of all contamination; Intersmooth 7476Si SPC must be applied within the specified recoat interval (refer to the relevant product Data Sheet). Areas of damage or breakdown must be prepared to the specified standard (e.g. Sa2.5 (ISO 8501-1:2007)) and primed before application of Intersmooth 7476Si SPC.
Major repair: Intersmooth 7476Si SPC must always be applied over the recommended primer. The primer surface must be dry and free of all contamination; Intersmooth 7476Si SPC must be applied within the specified recoat interval (refer to the relevant product Data Sheet).
Areas of damage or breakdown must be prepared to the specified standard (e.g. SSPC-SP10) and primed before application of Intersmooth 7476Si SPC.
Repair: Intersmooth 7476Si SPC applied over itself: as soon as the vessel enters dry dock and before it dries, wash the entire area with high-pressure fresh water (3,000 psi, 211 kg/cm²) using a fan-jet lance held close to the surface. Refer to the recommended anticorrosive primer system and apply Intersmooth 7476Si SPC within the primer's specified recoat interval (refer to the relevant primer Data Sheet).
Intersmooth 7476Si SPC applied over International tin-free antifouling, International Intersmooth SPC antifouling or a competitor's antifouling: consult the local International representative for specific advice.
This coating is a single-component product; stir thoroughly with a power mixer before application.
Normally no thinning is required. Under extreme conditions, consult your local representative for application advice. Do not thin beyond the limits of local environmental regulations.
Recommended nozzle size 0.54–0.8 mm (21–31 thou); total output fluid pressure at the nozzle not less than 190 kg/cm² (2700 psi)
Conventional spray application is not recommended.
Brush application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Roller application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Flush all equipment thoroughly with International thinner. All unused paint must be stored in tightly closed containers. Partly filled containers may show increased viscosity after storage. Strain the paint before use.
If welding or flame cutting is performed on metal coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation.
All work related to the application and use of this product must comply with national health, safety and environmental protection standards and regulations.
Before using this product, obtain, read and follow the health and safety information in the Material Safety Data Sheet for the product. Read and observe all precautions in the Material Safety Data Sheet and on the container label.

The service life of the coating is directly proportional to the applied thickness. Product performance depends on achieving the specified film thickness.
After immersion, the colour of Intersmooth 7476Si SPC shows slight change.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
Apply in good weather. The temperature of the surface to be coated shall be at least 3 °C above the dew point. Unless otherwise instructed, keep the paint at 21 °C before mixing and application for optimum performance. Unmixed paint (in tightly closed containers) shall be stored as specified in the 'Storage' section of this data sheet.
