Certification

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

• Food Contact - Carriage of Grain (NOHA)
• Food Contact - FDA Compliant: Dry Foodstuffs
• Fire Resistance - Marine Equipment Directive compliant

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. When using in cargo holds, consult the Interbond 501 Cargo Hold Application Guidelines.

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.

MAJOR REFURBISHMENT

Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Interbond 501, 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. Interbond 501 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2M.

REPAIR/OBM - Exposed steel and corrosion:

Hand or power tool clean to a minimum St2 (ISO 8501-1:2007). Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun should be spot blasted to a minimum standard of Sa2 (ISO 8501-1:2007). Typically this would apply to C or D grade steel in this standard.

Or Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Interbond 501, 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.

Or Interbond 501 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2M. Interbond 501 is suitable for overlap onto most aged coating systems. Loose or flaking coatings should be removed back to a firm edge and Interbond 501 should be applied to overlap the existing coating by 2-3 centimetres (one inch). Glossy epoxies and polyurethanes may require abrasion.

Intact Coatings:

This product may be applied as a full coat over most generic types of paint that have been aged for at least 3 months. It is advisable that a small trial be carried out before applying a full coat over certain generic types. Consult International Paint for acceptable generic types and extent of surface preparation required. Accurate film thickness control is essential, particularly when overcoating existing systems. Consult your International Paint representative for specific recommendations.

APPLICATION

Mixing

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

Thinner

Not recommended. Use International GTA220 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 176 kg/cm2 (2500 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 GTA220/GTA822

Work Stoppages and Cleanup

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

For wet holds and boottops: abrasive blast clean to Sa21⁄2 (ISO8501-1 : 1988) or SSPC-SP10. If oxidation has occurred between blasting and application of Interbond 501, 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. Apply one coat of the recommended primer. Interbond 501 must be applied within the overcoating interval specified on the primer product data sheet. Interbond 501 is not recommended for application below 10°C. For dry holds, decks, deck fittings and topsides: optimum performance is achieved when this coating is applied over blasted steel. When spraying large areas, application of a brush coat is recommended over pitted or rough surfaces to ensure full penetration. Stripe coating of complex structures is recommended. In common with all epoxy based coatings Interbond 501 will exhibit chalking of the film on UV exposure. 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.
