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).
When used as part of an approved scheme, the product holds the following certificates: the product is approved by the following classification societies in compliance with the International Convention on the Control of Harmful Anti-fouling Systems on Ships, 2001 (AFS 2001): • Bureau Veritas • DNV GL • Lloyd's Register. For details, consult the local representative.
For the paint system best suited to the surface to be protected, consult your local 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.
Newbuildings: Intersmooth 7475Si SPC must always be applied over the recommended primer. The primer surface must be dry and free from any contamination, and Intersmooth 7475Si SPC must be applied within the specified recoating interval (refer to the relevant product data sheet). Areas of breakdown, damage, etc. must be prepared to the specified standard (e.g. Sa 2.5 (ISO 8501-1:2007)) and primed before applying Intersmooth 7475Si SPC.
Major repair: Intersmooth 7475Si SPC must always be applied over the recommended primer. The primer surface must be dry and free from any contamination, and Intersmooth 7475Si SPC must be applied within the specified recoating interval (refer to the relevant product data sheet).
Areas of breakdown, damage, etc. must be prepared to the specified standard (e.g. SSPC-SP10) and primed before applying Intersmooth 7475Si SPC.
Maintenance: Intersmooth 7475Si SPC applied over itself: as soon as the ship enters dry dock, wash the entire area with dense high-pressure fresh water (3,000 psi, 211 kg/cm²) using a fan jet held close to the surface, before it dries. Refer to the recommended anticorrosive primer system and apply Intersmooth 7475Si SPC within the recoating interval specified for the primer (refer to the relevant primer product data sheet).
Applying Intersmooth 7475Si SPC over International Paint tin-free antifouling, International Paint Intersmooth SPC antifouling, or competitors' antifouling: consult the local representative for specific recommendations.
This coating is a single-component product; stir thoroughly with a power mixer before application.
Not recommended. Only in special cases, use International GTA007 (maximum 5% by volume). 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.
Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations.
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. If these warnings and requirements are not fully understood, or cannot be strictly observed, do not use the product. During application and drying of the product, provide adequate ventilation and protective measures to keep solvent vapour concentrations within safe limits, so as to prevent poisoning or oxygen deficiency. Take protective measures to avoid skin and eye contact with the product (e.g. gloves, goggles, face shield, barrier cream). Specific safety measures depend on the application method and working environment.

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 7475Si SPC may change slightly.
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 must be at least 3 °C above the dew point. Unless otherwise specifically instructed, raise the paint temperature to between 21 and 27 °C before mixing and application to achieve optimum application performance. Unmixed paint (in sealed containers) must be stored protectively as specified in the Storage section of this product data sheet. The technical and application data given here are intended as general guidance for establishing an application procedure. Test results are obtained in a controlled laboratory environment, and International Paint does not claim that the published test results, or any other test results, accurately represent results obtained in all site environments. Because application, environmental and design parameters vary widely, care must be exercised in coating selection, performance verification and use.
