Drying and overcoating information (typical)
Substrate temperature and film build influence drying; the following values apply to typical thicknesses within the recommended range:
- Touch dry (ISO 9117/3:2010):
- -5°C: 6 hours
- 5°C: 4 hours
- 25°C: 2.5 hours
- 35°C: 2 hours
- Minimum time before flooding (single coat systems):
- -5°C: 30 hours
- 5°C: 12 hours
- 25°C: 8 hours
- 35°C: 7 hours
If any antifouling coat exceeds 150 microns dft and/or total antifouling thickness at major refurbishment or repair exceeds 300 microns, the minimum time to flooding must be increased to 24 hours between 5°C and 20°C and to 18 hours at 25°C and above.

Applications and use cases
Intended environments
- Deep sea trading vessels where long-term fouling control and linear polishing performance are required.
- Newbuildings: applied over a recommended anticorrosive primer scheme within the specified overcoating intervals.
- Major refurbishment/drydocking: used as part of a repair or upgrade antifouling system on existing hulls.
Surface preparation and compatibility
- Use in accordance with standard Worldwide Marine Specifications.
- All surfaces must be clean, dry and free from oil, grease and contamination; high pressure fresh water wash and SSPC-SP1 solvent cleaning are referenced.
- For newbuilding, apply over a recommended primer system; damaged areas should be prepared to standards such as Sa2½ (ISO 8501-1:2007) and reprimed before application.
- For major refurbishment, breakdown areas should typically be prepared to SSPC-SP10 before priming and overcoating.
- For application over existing INTERCEPT 7000, carry out close high-pressure fresh water washing (around 3,000 psi / 211 kg/cm²) as soon as the vessel enters dock, then apply the specified anticorrosive primer and INTERCEPT 7000 within the relevant overcoating interval.
- For application over other International Paint antifoulings or competitor antifoulings, specific recommendations are required from the supplier.
Application notes
- Thorough power agitation is required before application.
- Airless spray: tip size typically 0.54–0.80 mm (21–31 thou); fluid pressure at spray tip not less than 190 kg/cm² (2700 psi).
- Brush and roller application are recommended only for small areas; multiple coats may be needed to achieve specified film thickness.
- Apply in good weather conditions with the substrate temperature at least 3°C above the dew point. For optimum application properties, bring material to 21–27°C prior to use.
- On immersion the coating may exhibit a slight colour change.

Section 8 – Personal protective measures
INTERCEPT 7000 Brown is a flammable, hazardous coating. During storage, handling, mixing, application and surface preparation, strict adherence to health, safety and environmental guidance is essential.
Engineering controls
- Use only with adequate ventilation; employ local exhaust or process enclosures to keep airborne concentrations below occupational exposure limits.
- Ventilation and equipment must be explosion-proof to control solvent vapour concentrations below lower explosive limits.
- Ensure eyewash stations and safety showers are close to work areas.
General hygiene measures
- Avoid eating, drinking and smoking in areas where the product is handled or applied.
- Wash hands, forearms and face thoroughly after handling and before breaks.
- Remove contaminated clothing and protective equipment before entering eating areas; wash contaminated garments before reuse.
Eye and face protection
- Wear chemical splash goggles and/or a face shield conforming to an approved standard whenever there is a risk of liquid splashes, mists or vapours.
- If inhalation hazards exist, a full-face respirator may be required instead of goggles.
Hand protection
- Wear chemical-resistant, impervious gloves complying with relevant standards.
- For prolonged or frequently repeated contact, use gloves with protection class 6 (breakthrough time >480 minutes, EN374). Recommended materials: Viton or nitrile, thickness ≥0.38 mm.
- For short, incidental contact, use at least protection class 2 gloves (breakthrough time >30 minutes). Recommended: nitrile gloves, thickness ≥0.12 mm.
- Replace gloves regularly and immediately if damaged; note that breakthrough times vary between manufacturers.
Body and other skin protection
- Select protective clothing based on the specific task and risk; garments should be approved by a safety specialist before use.
- Where ignition risk from static discharge exists, wear anti-static protective clothing including overalls, boots and gloves (refer to EN 1149 for design and material requirements).
- Use appropriate safety footwear and any additional skin protection as required by the work environment.
Respiratory protection
- Based on the assessed hazards and exposure potential, wear a respirator that meets the appropriate standard or certification.
- Typically a half-mask respirator to EN140 fitted with type A/P2 or better filter is indicated during spraying or where solvent vapour and particulates may be present.
- Dry sanding, flame cutting or welding of the dry paint film will generate hazardous dusts and fumes; wet sanding/flatting is preferred. If exposure cannot be controlled by local exhaust, suitable respiratory protection is required.
Environmental exposure controls
- Check emissions from ventilation and process equipment to ensure compliance with environmental legislation.
- Where necessary, use fume scrubbers, filters or process modifications to minimise solvent and particulate release.
- Prevent contamination of drains, soil and watercourses, as the product is very toxic to aquatic life with long lasting effects.
