Note

At temperatures <15°C, a coat of Intergard 263 is required prior to the application of Interthane 990. At temperatures between 15°C and 40°C, Interthane 990 can be applied direct, in accordance with the overcoating intervals stated. For application of Interthane 990 at temperatures in excess of 40°C consult your International Paint representative.

REGULATORY DATA

VOC 222 g/lt as supplied (EPA Method 24) 129 g/kg of liquid paint as supplied. EU Solvent Emissions Directive (Council Directive 1999/13/EC)

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:
• Food Contact - Carriage of Grain (NOHA)
• Food Contact - FDA Compliant: Dry Foodstuffs
Consult your International Paint representative for details.

SYSTEMS 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.

MAJOR REFURBISHMENT

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 Intershield 803, 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 the underwater hulls, abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) is required.

REPAIR AND NEWBUILDING

Consult your International Paint representative for specific recommendations. For spot repairs, Intershield 803 may be applied by brush or roller over areas less than 2m², prepared by power tooling, provided a minimum surface profile of 50μm is achieved. Several coats may be required to achieve the correct film thickness.

 

APPLICATION

Mixing

Material is supplied in 2 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 B and mix thoroughly with a power agitator.

Thinner

Not recommended unless thinning for use as a holding primer or applying at temperatures below 10°C. In these cases, use GTA220 at 5% by volume. DO NOT thin more than allowed by local environmental legislation. (If used as a holding primer below 10°C, 10% thinner should be used).

Airless Spray

Recommended
Tip Range 0.53-0.66 mm (21-26 thou)
Total output fluid pressure at spray tip not less than 211 kg/cm² (3000 p.s.i.)

Brush

Not recommended.

Roller

Not recommended.

Cleaner

International GTA822

Work Stoppages and Cleanup

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

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. Intershield 803 will cure down to -5°C but will require a period of cure above 5°C to achieve full mechanical properties. Consult International Paint.

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.
