Regulatory data

VOC

529 g/lt as supplied (EPA Method 24) 498 g/kg of liquid paint as supplied. EU Solvent Emissions Directive (Council Directive 1999/13/EC)

Note.

VOC values are typical and are provided for guidance purposes only. These may be subject to variation depending on factors such as differences in colour and normal manufacturing tolerances.

CERTIFICATION

When used as part of an approved scheme, this product has the following certification: When tested in accordance with ASTM D5108-96 (modified) Intertuf 203 forms a barrier to TBT leaching from an underlying TBTantifouling. Long term testing is ongoing. Consult your International Paint representative for details.

System and compatibility

Consult your International Paint representative for the system best suited for the surfaces to be protected.

Surface preparations

Use in accordance with the standard Worldwide Marine Specifications. All surfaces to be coated should be clean, dry and free from contamination. High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.

NEWBUILDING

Where necessary, remove weld spatter and smooth weld seams and sharp edges. Weld seams and damaged areas should be blast cleaned to Sa21⁄2 (ISO 8501-1:2007) or power tooled to Pt3 (JSRA SPSS:1984) For PVB and unapproved shop primers, the surface should be blast cleaned to Sa21⁄2 (ISO 8501-1:2007) For iron oxide epoxy shop primers, ensure the intact primer is clean and dry. Weld seams and damaged areas should be prepared to the specified standard (eg. Sa21⁄2 ISO 8501-1:2001). For high zinc primers, grit sweep to AS2 International Paint Sweep Blast Standards or power tool to Pt3 (JSRA SPSS:1984). For blasted areas, the primer should be applied before oxidation occurs. If oxidation does occur, the entire oxidised area should be reblasted to the specified standard above. On split anticorrosive schemes, where Intertuf 203 has weathered, please consult International Paint.

MAJOR REFURBISHMENT

Abrasive blast clean to Sa21⁄2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intertuf 203, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner. Consult your International Paint representative for specific recommendations.

APPLICATION

Mixing

This material is a one pack coating and should always be mixed thoroughly with a power agitator before application.

Thinner

Not recommended. Use International GTA007 only in exceptional circumstances. DO NOT thin more than allowed by local environmental legislation.

Airless Spray

Recommended Tip Range 0.53-0.66 mm (21-26 thou) Total output fluid pressure at spray tip not less than 211 kg/cm2 (3000 p.s.i.)

Conventional Spray

Application by conventional spray is not recommended.

Brush

Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.

Roller

Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.

Cleaner

International GTA007

Work Stoppages and Cleanup

Thoroughly flush all equipment with International GTA007. All unused material should be stored in tightly closed containers. Partially filled containers may show surface skinning and/or a viscosity increase of the material after storage. Material should be filtered prior to use.

Welding

In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation. In North America do so in accordance with instruction in ANSI/ASC Z49.1 "Safety in Welding and Cutting."

SAFETY

All work involving the application and use of this product should be performed in compliance with all relevant national Health, Safety & Environmental standards and regulations. Prior to use, obtain, consult and follow the Material Safety Data Sheet for this product concerning health and safety information. Read and follow all precautionary notices on the Material Safety Data Sheet and container labels. If you do not fully understand these warnings and instructions or if you can not strictly comply with them, do not use this product. Proper ventilation and protective measures must be provided during application and drying to keep solvent vapour concentrations within safe limits and to protect against toxic or oxygen deficient hazards. Take precautions to avoid skin and eye contact (ie. gloves, goggles, face masks, barrier creams etc.) Actual safety measures are dependant on application methods and work environment.

Limitations

Optimum performance is achieved when Intertuf 203 is applied over blasted steel. Intertuf 203, JVA202 aluminium must be specified as the first coat in an anticorrosive system. Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions. Consult your local International Paint representative for specific recommendations. Apply in good weather. Temperature of the surface to be coated must be at least 3°C above the dew point. For optimum application properties bring the material to 21-27°C, unless specifically instructed otherwise, prior to mixing and application. Unmixed material (in closed containers) should be maintained in protected storage in accordance with information given in the STORAGE Section of this data sheet. Technical and application data herein is for the purpose of establishing a general guideline of the coating application procedures. Test performance results were obtained in a controlled laboratory environment and International Paint makes no claim that the exhibited published test results, or any other tests, accurately represent results found in all field environments. As application, environmental and design factors can vary significantly, due care should be exercised in the selection, verification of performance and use of the coating.
