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).
The product complies with the International Convention on the Control of Harmful Anti-fouling Systems on Ships adopted by the IMO (AFS 2001).
External approvals may depend on formulation and/or production plant; consult your local representative for details.
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.
Newbuild/overhaul: Intersmooth 7670 SPC should always be applied over a recommended primer. The primer surface should be dry and free of any contaminants; Intersmooth 7670 SPC must be applied within the specified overcoating interval (see the relevant product data sheet). Damaged areas etc. shall be treated to the specified standard (e.g. Sa 2.5 (ISO 8501-1:2007)), and primed before applying Intersmooth 7670 SPC.
Repair: Intersmooth 7670 SPC self-overcoat: as soon as the vessel enters dry dock, before it dries, use a fan jet spray gun close to the surface to spray dense high-pressure fresh water (3000 lb/in², 211 kg/cm²) to wash and clean the entire area.
For other surface preparation options, consult International Paint.
For corroded areas, use the recommended primer system and apply Intersmooth 7670 SPC within the specified overcoating interval (see the corresponding primer's product data sheet). For applying Intersmooth 7670 SPC over International Paint's tin-free self-polishing or competitors' antifouling paints, consult your 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 tip size 0.63–0.79 mm (25–31 thou); total fluid pressure at the nozzle not less than 211 kg/cm² (3000 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. In North America, follow the instructions in ANSI/ASC Z49.1 “Safety in Welding and Cutting”.
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).

Do not expose the coated surface to sunlight for a long time. Prolonged sunlight exposure may affect the antifouling performance of the paint.
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.
