SYSTEMS AND COMPATIBILITY
Consult your International Paint representative for the system best suited for the surfaces to be protected.
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.
Abrasive blast clean to Sa2 (ISO 8501-1:2007). A blast profile of 75μ - 100μ is required. If oxidation has occurred between blasting and application of Intergard 7020, 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.
For application to ballast holds, abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) is required.
REPAIR/OBM - Exposed steel and corrosion:
Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intergard 7020, 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.
Intergard 7020 is suitable for overlap onto most aged coating systems. Loose or flaking coatings should be removed back to a firm edge and Intergard 7020 should be applied to overlap the existing coating by 2-3 centimetres (one inch). Existing coatings may require abrasion.
This product may be applied as a full coat over most generic types of paint that have been aged for at least 3 months, abrasion may be required. 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.
Abrasive blast clean to Sa2½ (ISO 8501-1:2007).
Consult your International Paint representative for specific recommendations.
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.
ThinnerUse International GTA220. Do not thin more than allowed by local environment legislation.
Tip Range 0.53-0.63 mm (21-25 thou)
Total output fluid pressure at spray tip not less than 281 kg/cm² (4000 p.s.i.)
Application by conventional spray is not recommended.
Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.
Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.
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 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.
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."
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.
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. Optimum performance is achieved when Intergard 7020 is applied over blasted steel. Intergard 7020 will cure down to -5°C but will require a period of cure above 5°C to achieve full mechanical properties. Consult International Paint.
The coating will exhibit surface discolouration if immersed in seawater after application and curing at temperatures <10°C. This does not effect the performance characteristics of the product. 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.
In the overcoating data section 'ext' = extended overcoating period. Please refer to our Marine Painting Guide - Definitions and Abbreviations available on our website.
