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.
Intersleek 731 shall always be applied over the recommended primer. The primer surface shall be dry and free from any contaminants. Intersleek 731 must be applied within the specified overcoating interval (refer to the relevant product data sheet). Areas of damage or defect shall be prepared to the specified standard (e.g. Sa2.5 (ISO 8501-1:2007)) and primed before application of Intersleek 731.
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)
Apply by airless spray. Brush application requires multiple coats and is recommended only for small areas for stripe coating. Applying 160 µm wet film thickness will produce 100 µm dry film thickness. Refer to the equipment recommendations below or use other suitable equivalent equipment.
The coating is supplied in two containers as one unit. Always mix the entire unit in the supplied ratio. Once mixed, use within the specified pot life.
(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the base (Component A) with the curing agent (Component B) and stir thoroughly with a power mixer.
Not recommended. Only in special cases, use International GTA007. Do not thin beyond the limits of local environmental regulations.
Recommended nozzle size 0.38–0.53 mm (15–21 thou); total output fluid pressure at the nozzle not less than 211 kg/cm² (3000 psi)
Conventional spray application is not recommended.
Brush application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Not applicable.
Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch before resuming application.
All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during the day is good working practice. Cleaning frequency depends on the volume sprayed, temperature and time in use (including delays). Do not exceed the pot life of the paint.
All surplus paint and empty containers must be disposed of in accordance with appropriate local regulations/laws.
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. 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.

Take care to avoid overspray on other coated areas.
All equipment must be thoroughly cleaned before use or before reuse with other paints to prevent contamination. Liquid cleaners used for Intersleek 731 must not contaminate other paints.
Apply in good weather with air and surface temperatures above 15 °C. Surface temperature must be at least 3 °C above the dew point. For optimum application properties, raise the paint temperature to between 21–27 °C before mixing and application.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
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.
