System and compatibility

For the paint system best suited to the surface to be protected, consult your local International Paint representative.

For cargo oil tanks, refer to the Interline 624 cargo oil tank application procedure.

For ballast tanks, refer to the Interline 624 ballast tank application procedure.

Surface Preparation

Applied in accordance with the standard Worldwide Marine Specifications.

All surfaces to be coated must be clean, dry and free of contaminants.

Wash with high-pressure or ordinary fresh water as appropriate, and remove all oil, grease, soluble contaminants and other foreign matter in accordance with the SSPC-SP1 solvent cleaning standard.

Newbuilding/major repair: abrasive blast clean to Sa 2.5 (ISO 8501-1:2007). If oxidation occurs between blasting and application of Interline 624, the surface should be re-blasted to the specified pictorial standard.

Surface defects exposed by abrasive blasting must be ground, filled or treated by a suitable method.

Where required, remove weld spatter and grind welds and sharp edges smooth.

Welds and damaged areas shall be blast-cleaned to Sa2.5 (ISO 8501-1:2007) or power-tool cleaned to Pt3 (JSRA SPSS:1984).

For all shop primers, the surface should be blast cleaned to Sa 2.5 (ISO 8501-1:2007).

A sharp, angular surface profile of 50–100 µm is recommended.

For maintenance, consult International Paint.

Note: for marine environments in North America, the following surface preparation standards may be used: SSPC-SP10 instead of Sa 2.5 (ISO 8501-1:2007); SSPC-SP11 instead of Pt3 (JSRA SPSS:1984). Product mixing before application. Single-feed paint is supplied in two containers as a set. Always mix whole sets in the supplied ratio. Once a set is mixed, it must be used within the specified mixed application time.

(1) Before mixing, the temperature of Components A and B should be 20-25 °C. Excessively high component temperatures will shorten the mixed application time. If the temperature of the two components exceeds 30 °C, plural-component airless spray equipment is recommended.

(2) Stir the base (Component A) with a power mixer.

(3) Stir the curing agent (Component B) with a power mixer.

(4) Mix all of the curing agent (Component B) with the base (Component A) and stir thoroughly with a power mixer.

(5) Use quickly within the specified mixed application time.

Plural-feed: (1) Before application, do not mix the base (Component A) and curing agent (Component B).

(2) The base (Component A) should be circulated through the airless spray unit and heated to 30-40 °C by an in-line heater.

(3) The curing agent (Component B) should be kept at at least 20 °C.

Welding or flame cutting on metal coated with Interline 624: if welding or flame cutting is carried out on metal coated with this product, dust and fumes will be emitted, requiring suitable personal protective equipment and local exhaust ventilation. In North America, operate in accordance with ANSI/ASC Z49.1 "Safety in Welding and Cutting".

Application

Thinner

Do not thin.

Airless Spray

Ensure the spray gun rate exceeds the maximum fluid output pressure of the pump in use.

Single-feed - nozzle size 0.013 in-0.019 in (330-483 µm). Smaller nozzles provide better control of primer film thickness.

- Total fluid pressure at the nozzle not less than 5000 lb/in² (352 kg/cm²). - Minimum pump ratio 70:1. It is recommended to install an in-line heater as close as possible to the fluid outlet of the pump. This allows the operator to use heat to improve the flow of the coating through long paint hoses. To achieve a paint temperature of 28-32 °C at the spray gun, a heater should be installed. The heater in the line must not be installed too high.

The recommended hose length should be as short as possible and not exceed 150 ft (46 m). A 3/8 in (9.5 mm) inner diameter paint hose and a 1/4 in (6.4 mm) inner diameter end whip achieve ideal results.

Plural-feed - total fluid pressure at the nozzle not less than 3500 lb/in² (246 kg/cm²). - The base (Component A) should be recirculated through the spray unit and heated to 30-40 °C by an in-line heater. - The curing agent should be kept at at least 20 °C.

- Nozzle size 0.013 in-0.019 in (330-483 µm). Smaller nozzles provide better control of primer film thickness.

- The mixed paint line should be kept as short as possible. When using plural-component spray equipment, it is important to ensure an adequate supply of each component to the main metering unit. If feed pumps are used, they should be carefully installed to maintain a normal supply of Components A/B and prevent cavitation in the feed hoses. Otherwise, incorrect mixing ratios may result, leading to slow curing, cracking, micro-cracking and adverse effects on mechanical properties.

Conventional spray

Conventional spray application is not recommended.

Brush

Brush application is recommended for small areas only.

Roller application

Roller application is recommended for small areas only.

Cleaner

International GTA822/GTA415

Interruption of work and cleaning

Do not let coating remain in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA822/GTA415. Once a set of paint is mixed, it should not be resealed; if the interruption during application is too long, remix the components before resuming application.

All equipment should be cleaned with International GTA822/GTA415 immediately after use. Periodically flushing spray equipment during the working day is good practice. The number of cleanings depends on spray volume, temperature and usage time (including idle time). Do not exceed the mixed application time of the coating.

All surplus paint and empty containers must be disposed of in accordance with appropriate local regulations/laws.

For plural-component application, it is important to flush the static mixer in the line, the paint mixing hose and the spray gun when work is interrupted for more than 10 minutes.

Welding

Limitation

At ambient temperatures below 25 °C, the gun feed line must be insulated.

The product does not cure adequately below 10 °C.

Drying times and overcoating intervals may vary with site factors such as tank geometry and ventilation rate.

For the interval required between completion of coating and ballasting, consult an International Paint representative.

Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.

Apply in good weather. The temperature of the surface to be coated must be at least 3 °C above the dew point. Unless otherwise specified, for ideal application performance, raise the paint temperature to between 20-25 °C before mixing and application. Unmixed paint (in tightly closed containers) should be stored protectively in the manner specified in the "Storage" section of the product data sheet. The technical and application data mentioned here are intended to form a general procedure for developing a coating application process. Test performance results come from a controlled laboratory environment; International Paint does not claim that the published test results, or any other tests, accurately represent results obtained in all field environments. Because application, environmental and design parameters vary greatly, great care should be exercised in coating selection, performance verification or use.
