Coating hazards GB 30981.2-S-Pb≤1000-NC; complies with GB 30981.2-2025
For the paint system best suited to the surface to be protected, consult your local International Paint representative.
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 refurbishment: Interlac 497 should always be applied over the recommended primer. The primer surface should be dry and free from any contamination, and Interlac 497 must be applied within the specified recoat interval (refer to the relevant product Data Sheet). Areas of damage or defects should be prepared to the specified standard (e.g. Sa2.5 (ISO 8501-1:2007)) and primed before application of Interlac 497.
Repair: touch up corroded areas with a suitable International Paint primer (refer to the primer Data Sheet).
For specific advice, consult your local International Paint representative.
This coating is a single-component product; stir thoroughly with a power mixer before application.
International GTA004. Normally no thinning is required. Under extreme conditions, consult your local representative for application advice. Do not thin beyond the limits of local environmental regulations.
Recommended nozzle size 0.38–0.46 mm (15–18 thou); total fluid output pressure at the nozzle not less than 176 kg/cm² (2500 psi)
Suitable.
Use suitable dedicated equipment. Thinning may be required.
Flush all equipment thoroughly with International thinner. All unused paint must be stored in tightly closed containers. Partly filled containers may show skinning and/or increased viscosity after storage. Strain the paint before use.
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”.
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.

Interlac 497 is not suitable for immersed areas.
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.
