When used as part of an approved scheme, the product holds the following certificates: when tested in accordance with ASTM D5108-96 (modified), Intertuf 203 forms a barrier to TBT leaching from the tin-containing antifouling paints listed below. Long-term testing is ongoing.
Food contact – carriage of grain (NOHH). For details, consult the local International Paint representative.
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.
On newbuildings, remove weld spatter and grind welds and sharp edges smooth where required.
Welds and damaged areas shall be blast-cleaned to Sa2.5 (ISO 8501-1:2007) or power-tool cleaned to Pt3 (JSRA SPSS:1984).
For PVB (polyvinyl butyral) and unapproved shop primers, the surface shall be abrasive blast cleaned to Sa2.5 (ISO 8501-1:2007).
For iron oxide epoxy shop primer, ensure the entire primer surface is clean and dry. Welds and damaged areas shall be prepared to the specified standard (e.g. Sa2.5, ISO 8501-1:2001).
For primers with a high zinc content, sweep blast to International Paint Sweep Standard AS2 or power tool clean to Pt3 (JSRA SPSS:1984).
Blasted areas should be primed before oxidation occurs. If oxidation has occurred, the entire oxidised area must be re-blasted to the specified standard.
For block-assembly anti-corrosion schemes where Intertuf 203 has weathered, consult International Paint.
Major repair: abrasive blast clean to Sa2.5 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intertuf 203, the surface shall be re-blasted to the specified pictorial standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by a suitable method.
For specific advice, consult your local International Paint representative.
Note: for marine environments in North America, the following surface preparation standards may be used: SSPC-SP10 in place of Sa2.5 (ISO 8501-1:2007), SSPC-SP11 in place of Pt3 (JSRA SPSS:1984).

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 skinning and/or 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). Specific safety measures depend on the application method and working environment.

Optimum performance is achieved when Intertuf 203 is applied to abrasive blast cleaned steel.
Intertuf 203, JVA202 aluminium, shall be specified as the first coat of the anti-corrosion system.
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.
