When used as part of an approved scheme, this product holds the following certificates: • Fire resistance - complies with the 'Marine Equipment Directive'. • Fire resistance - 'smoke and toxicity' (Exova Warringtonfire). • Fire resistance - complies with low flame spread requirements (Exova Warringtonfire). • Fire resistance - complies with low flame spread requirements (WFR) - (BS 476 Part 7). • Food contact - grain loading (NOHH). For details, consult the local representative.
For the paint system best suited to the surface to be protected, consult your local 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.
For refurbishment, abrasive blast cleaning to Sa2 (ISO 8501-1:2007). If oxidation occurs between blasting and application of Interseal 670HS, the surface shall be re-blasted to the specified pictorial standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by a suitable method.
Interseal 670HS may be applied over surfaces prepared to the International Paint ultra-high-pressure water cleaning standard HB2, with flash rust to a standard not lower than HB2M.
Repair/in-service maintenance — exposed steel and corrosion: clean by hand or power tool at least to St2 (ISO 8501-1:2007).
Note: all mill scale shall be removed; areas not suitably treated by chipping or needle gun shall be spot-blasted at least to Sa2 (ISO 8501-1:2007).
Generally, this method is suitable for grade C or D steel.
Or abrasive blast cleaning to Sa2 (ISO 8501-1:2007). If oxidation occurs between blasting and application of Interseal 670HS, the surface shall be re-blasted to the specified pictorial standard.
Or Interseal 670HS may be applied over surfaces prepared to the International Paint ultra-high-pressure water cleaning standard HB2, with flash rust to a standard not lower than HB2M.
Interseal 670HS is suitable for application over most old coating systems. Loose or flaking coatings shall be removed to a firm edge, and Interseal 670HS shall be applied with an overlap of 2–3 cm (1 in) onto the existing coating. Glossy epoxy and polyurethane may require abrading.
Full coat: this product may be applied as a full coat over most general types of existing coatings at least 3 months old. A patch test is recommended before full application over a given generic coating type. For acceptable coating types and the degree of surface preparation required, consult International Paint.
Precise control of film thickness is critical, especially when recoating existing coating systems.
For specific advice, consult your local representative.
Note: for marine environments in North America, the following surface preparation standards may be used: SSPC-SP6 in place of Sa 2 (ISO 8501-1:2007); SSPC-SP2 in place of St 2 (ISO 8501-1:2007); SSPC-SP10 in place of Sa 2.5 (ISO 8501-1:2007).
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.
Use International GTA220 only in special cases. Do not thin beyond the range permitted by local environmental regulations.
Recommended nozzle tip size 0.45–0.58 mm (18–23 thou); total fluid pressure at the nozzle not less than 176 kg/cm² (2500 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.
Roller application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations.
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.

When applied in cargo holds, the application and curing temperature shall be above 10 °C for the coating to reach optimum mechanical properties.
When spraying large areas, apply a brush coat over pitted or rough surfaces to ensure full penetration. Touch-up of complex members is recommended.
Interseal 670HS is not suitable for ballast tanks.
Contact the local International Paint representative for underwater hull coating systems.
Interseal 670HS achieves optimum performance when applied over blast-cleaned steel.
If salt water is used during wet blasting, the prepared surface shall be washed thoroughly with fresh water before applying Interseal 670HS. Light spot rust on freshly blasted surfaces is preferable to a surface that is too wet. Puddles, stagnant water and standing water shall be removed.
As with all epoxy-based coatings, Interseal 670HS chalks when exposed to UV light.
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.
