Certificates

When used as part of an approved scheme, this coating holds the following certificates: • Ice Class – approved abrasion-resistant ice coating (LR) • Ice Class – type approval certificate for ships operating in ice (TAC) (BV) • Food contact – grain cargo (NOHH). For details, consult the local International Paint representative.

System and compatibility

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

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: abrasive blast clean to Sa2.5 (ISO 8501-1:2007). If oxidation occurs between blasting and application of Intershield 163 Inerta 160, re-blast to the specified pictorial standard.

For information on the required blast profile, refer to the Intershield 163 Inerta 160 application guide.

Refit: abrasive blast clean to Sa2.5 (ISO 8501-1:2007). If oxidation occurs between blasting and application of Intershield 163 Inerta 160, re-blast to the specified pictorial standard.

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

For specific advice, consult your local International Paint representative.

Note: for the marine environment in North America, the following surface preparation standard may be used: SSPC-SP10 in place of Sa 2.5 (ISO 8501-1:2007)

Application

Apply by twin-feed airless hot spray only. Refer to the detailed application procedure. Consult International Paint.

Twin-feed hot spray: pump with minimum ratio 30:1 (45:1 ideal); delivery line minimum 3 GPM; nozzle tip 0.021–0.032 in (533–813 µm); high-pressure insulated paint hose with 3/8 in (9.5 mm) internal diameter; line pressure 90 psi; 60-mesh nozzle filter.

A solvent flush pump is also required.

Mixing

The coating is supplied in two containers as a set. Pre-heat cold-packed containers to reduce waste. Add each component to the corresponding hopper of the twin-feed airless spray machine.

Thinner

Do not thin! Thinning impairs the abrasion resistance of the coating. Acetone is used as the flushing solvent because of its very fast evaporation, minimising the effect of any residue left in curved hoses. It is also not listed under VOC regulations.

Brush

Brush application will require more than one coat and is recommended only for small-area touch-up.

Cleaner

Interruption of work and cleaning

Do not allow coating to remain in the hose; if work stops for more than 2 min, flush immediately. Flush hoses and spray gun thoroughly. Monitor the coating condition closely. Do not exceed the pot life after mixing.

Clean all equipment immediately after use with International GTA220/GTA822. Spray equipment must be flushed with acetone. Flushing spray equipment periodically during the working day is good practice. The number of flushings depends on the quantity sprayed, temperature and elapsed time (including delays).

At start-up, flush International GTA220/GTA822 through the lines. Dispose of all leftover coating and empty containers in accordance with local regulations/laws.

Welding

If welding or flame cutting is performed on metal coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation. In North America, follow the instructions in ANSI/ASC Z49.1 “Safety in Welding and Cutting”.

Safety

All work related to the application and use of this product must comply with national health, safety and environmental protection standards and regulations.

Before using this product, obtain, read and follow the health and safety information in the Material Safety Data Sheet for the product. Read and observe all precautions in the Material Safety Data Sheet and on the container label. If these warnings and requirements are not fully understood, or cannot be strictly observed, do not use the product. During application and drying of the product, provide adequate ventilation and protective measures to keep solvent vapour concentrations within safe limits, so as to prevent poisoning or oxygen deficiency. Take protective measures to avoid skin and eye contact with the product (e.g. gloves, goggles, face shield, barrier cream). Specific safety measures depend on the application method and working environment.

Limitation

Before application, raise the temperature of the components and mixed paint to between 45 °C and 50 °C by recirculation and heated lines.

This product does not cure adequately below 10 °C. For ideal performance, the curing ambient temperature should be above 10 °C.

For newbuildings, if the coating can cure for at least 2 months before delivery, this product can be applied at temperatures down to 0 °C.

Consult International Paint regarding curing time before launching and before entering ice waters.

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 specifically instructed, raise the paint temperature to between 21 and 27 °C before mixing and application to achieve optimum application performance. Unmixed paint (in sealed containers) must be stored protectively as specified in the Storage section of this product data sheet. The technical and application data given here are intended as general guidance for establishing an application procedure. Test results are obtained in a controlled laboratory environment, and International Paint does not claim that the published test results, or any other test results, accurately represent results obtained in all site environments. Because application, environmental and design parameters vary widely, care must be exercised in coating selection, performance verification and use.
