CERTIFICATION

When used as part of an approved scheme, this material has the following certification:

Product recognised by the following classification societies as compliant with the International Convention on the Control of Harmful Anti-fouling Systems on Ships, 2001 (AFS 2001):

  • Lloyd's Register
  • Germanischer Lloyd
  • Korean Register of Shipping
  • Det Norske Veritas
  • Bureau Veritas

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.

Intersleek 425 must always be applied over Intersleek 386 tie coat (Intersleek 381 tie coat in USA) within the required overcoating interval.
Consult International Paint for detailed application advice and recommendations.

APPLICATION

Mixing

Material is supplied in 3 containers as a unit. Always mix a complete unit in the proportions supplied. (1) Agitate Part A with a power agitator. (2) Combine entire contents of Part A and Part B and mix thoroughly with a power agitator. (3) Add entire contents of Part C and mix thoroughly with a power agitator. Once the unit has been mixed, it must be used within the working pot life specified.

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 0.38-0.53 mm (15-21 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. Consult International Paint.

Roller

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

Cleaner

International GTA007/GTA822

Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA007/GTA822. Once units of paint have been mixed they should not be resealed and it is advised that after prolonged stoppages work recommences with freshly mixed units. Clean all equipment immediately after use with International GTA007/GTA822. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays. Do not exceed pot life limitations. All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation.

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

Minimum acceptable substrate temperature at the time of application is +5°C. A minimum Relative Humidity of 30% is required to ensure satisfactory curing. Longer cure times will be required if the Relative Humidity falls below 30%. Care should be taken to avoid overspray onto other coated areas. Intersleek 425 must be applied over Intersleek 386 tie coat (Intersleek 381 tie coat in USA) within the required overcoating interval. All equipment must be thoroughly clean prior to use, and before re-use with other materials, to prevent contamination. Liquid cleaners for Intersleek 425 must not be allowed to contaminate other paints.

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.
