International Intershield 803, two pack, abrasion resistant pure epoxy coating with excellent mechanical properties.

As a high performance two pack abrasion resistant pure epoxy coating to limit mechanical damage and subsequent corrosion. Suitable for use with controlled cathodic protection. For use at maintenance & repair.

Intershield 803 has also been formulated to cure quickly at lower temperatures and poor ventilation, conditions often found in shipyards during winter applications and when the hatch covers are closed on a freshly coated hold. During performance testing, Intershield 803 reached full cure much faster than standard epoxies.

Intershield 803 provides long term cost benefits. The higher initial investment is offset by a significant reduction in repair and maintenance at drydock and through life costs in comparison to a modified epoxy. Payback is in approximately 3 years.

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.

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 Sa2½ (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 our technical team on 0113 2455450 (option 2) or send a message to [email protected]
• 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 curing agent (Part B) with base (Part A) and mix thoroughly with 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.)

Conventional Spray

• Application by conventional spray is not recommended

Brush/Roller

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

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.

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.

Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions.

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.
