Systems & Compatibility

Consult our technical team on 0113 2455450 (option 2) or send a message to [email protected] for the system best suited for the surfaces to be protected.

Intergard 263 should only be applied over epoxy anticorrosive primers. The primer to be used will depend upon vessel area and application locations. Typical primers include:

• Intergard 343
• Intershield 300
• Intershield 803
• Intertuf 262
• Intertuf 362

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.

Intergard 263 should always be applied over a recommended primer coating system.

Intergard 263 should be used in accordance with the specification given by International Paint.

The primer surface should be dry and free of all contamination (oil, grease, salt etc.) and overcoated with Intergard 263 within the overcoating intervals specified. Consult the relevant primer data sheet.

Application

Mixing

Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied.

• Agitate base (Part A) with power agitator.
• Combine entire contents of curing agent (Part B) with base (Part A) and mix thoroughly with power agitator.

Thinner

• International GTA220. Thinning is not normally required.
• Consult our technical team for advice during application in extreme conditions.
• Do not thin more than allowed by local environmental legislation.

Airless Spray

• Tip Range 0.46-0.66 mm (18-26 thou).
• Total output fluid pressure at spray tip not less than 176 kg/cm² (2500 p.s.i.)

Conventional Spray

• Application by conventional spray is not recommended.

Brush/Roller

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

Cleaner

• International GTA220/GTA822 
• International GTA415

Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA220/GTA822 or International GTA415. 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 GTA220/GTA822 or International GTA415. 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.

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 (see the attachments section above) 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

Spot Repair - The Intertuf 262/Intergard 263 system may be used for the spot repair of existing epoxy, coal tar epoxy, chlorinated rubber, vinyl tar and tar-free vinyl substrates. Feathered overlap areas must be kept to a minimum.

Consult Rawlins Technical. The Intertuf 262/Intergard 263 system is not suitable for repair of bituminous substrates. Upgrade - Intertuf 262/Intergard 263 may be used for the upgrade of existing epoxy, coal tar epoxy and chlorinated rubber substrates.

Substrates not suitable for upgrading:- vinyl tar, tar-free vinyl, bituminous.

Intergard 263 may be applied at substrate temperatures down to -15°C. Before applications are made below -5°C consult your local IP representative for further detail of application procedure.

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/Rawlins 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 under "Shelf Life" in the Product Information section. 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.
