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 material has the following Certification:

• Fire Resistance - Marine Equipment Directive compliant
• Fire Resistance - Surface Spread of Flame (WFR) - (IMO Resolution A653 (16))
• Fire Resistance - MSC61(67) Smoke & Toxicity (WFR)

Consult your International Paint representative for details.

System and compatibility

Interfine 878 must be applied over a recommended primer system, which will vary depending upon the vessel area. Direct application is acceptable over the following marine anticorrosives:

• Intershield 300
  
• Intergard 787
• Intergard 343

A tie coat of Intertuf 262/Intergard 282 or Intergard 269 may be required if Interfine 878 is to be applied over other epoxy primers. 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/MAJOR REFURBISHMENT

Interfine 878 should always be applied over a recommended primer coating scheme. The primer surface should be dry and free from all contamination, and Interfine 878 must be applied within the overcoating intervals specified (consult the relevant product data sheet). Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa21⁄2 (ISO 8501-1:2007)) and primed prior to the application of Interfine 878.

REPAIR/OBM

Interfine 878 should always be applied over a recommended primer coating scheme. The primer surface should be dry and free from all contamination, and Interfine 878 must be applied within the overcoating intervals specified (consult the relevant product data sheet). Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa21⁄2 (ISO 8501-1:2007)) and primed prior to the application of Interfine 878. Interfine 878 may be applied directly over aged Interfine 878 or Interfine 979 following thorough fresh water washing and degreasing provided the coating to be overcoated is in an intact and tightly adherent condition. Loose or flaking coatings should be removed back to a firm edge and Interfine 878 or an appropriate primer should be used to repair the area before application of the full coat. Consult your International Paint representative for specific recommendations.

APPLICATION

Mixing

Material is supplied in two 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 power agitator. (2) Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator. After mixing Part A and Part B a slight exotherm may be noted, which is typical of this product, and is a result of chemical reaction.

Thinner

International GTA007. Do not thin more than allowed by local environmental legislation.

Airless Spray

Recommended Tip Range 0.28-0.43 mm (11-17 thou) Total output fluid pressure at spray tip not less than 155 kg/cm2 (2200 p.s.i.)

Conventional Spray

Recommended. Gun Air Cap Fluid Tip DeVilbiss MCB or JGA 704 or 765 E

Brush

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

Roller

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

Cleaner

International GTA007

Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA007. 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. 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

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. The relative humidity should be between 40% and 85% for optimum cure of Interfine 878. Cure times may vary outside these parameters. 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.
