Drying and flooding times (per coat)
Substrate temperature -5°C / 5°C / 25°C / 35°C:
- Touch dry (ISO 9117/3:2010): 2 h / 90 min / 60 min / 30 min.

Applications and uses
Intended uses
- Specifically designed for deep sea vessels.
- Suitable for newbuilding and maintenance and repair projects.
- For use in Europe, North America and Korea (regional versions are available for other markets).
System compatibility
- To be used in accordance with standard Worldwide Marine Specifications.
- Always applied over a recommended primer coating scheme from International Paint.
- Primer surface must be dry and free from contamination and coated within the specified overcoating intervals.
Surface preparation
- General: All surfaces must be clean, dry and free from oil, grease, salts and other contaminants. High pressure fresh water wash or fresh water wash as appropriate, followed by solvent cleaning in accordance with SSPC-SP1.
- Newbuilding: Apply over the recommended primer. Areas of breakdown or damage should be prepared to Sa2½ (ISO 8501-1:2007) and re-primed before applying Intercept 8500 LPP.
- Major refurbishment: Apply over the recommended primer scheme. Damaged areas should be prepared to SSPC-SP10 (or specified standard) and re-primed prior to application.
- Repair over self: As soon as the vessel enters dry dock and before the hull dries, clean using close high pressure fresh water washing (3,000 psi / 211 kg/cm²) with a fan-jet lance. Apply the recommended anticorrosive primer where required and overcoat with Intercept 8500 LPP within the primer’s overcoating interval.
- Repair over other antifoulings: For use over International Paint TBT-free antifoulings, Intersmooth SPC or competitor antifoulings, specific guidance must be obtained from your International Paint representative.
Application guidelines

Section 8 – Individual protection measures
The following information is drawn from Section 8 of the Safety Data Sheet for Intercept 8500 LPP Blue and applies to handling and application of the product.
Engineering controls and hygiene
- Use only with adequate ventilation, employing process enclosures or local exhaust ventilation to keep exposure below recommended limits and below lower explosive limits.
- Ensure eyewash stations and safety showers are close to the work area.
- Wash hands, forearms and face thoroughly after handling, and before eating, drinking or smoking.
- Contaminated work clothing should not be allowed out of the workplace and must be washed before reuse.
Eye and face protection
- Use safety eyewear compliant with an approved standard whenever a risk assessment indicates potential exposure to liquid splashes, mists or vapours.
- Where contact is possible, wear chemical splash goggles and/or a face shield.
- If inhalation hazards exist and a full-face respirator is used, this may also provide eye protection.
Hand protection
- Wear chemical-resistant, impervious gloves compliant with an approved standard.
- For prolonged or frequently repeated contact, a glove with protection class 6 (breakthrough time >480 minutes according to EN374) is recommended. Suggested materials: Viton® or nitrile, thickness ≥0.38 mm.
- For brief contact, a glove with protection class ≥2 (breakthrough time >30 minutes according to EN374) is recommended. Suggested material: nitrile, thickness ≥0.12 mm.
- Replace gloves regularly and immediately if damaged.
Body and other skin protection
- Select protective clothing based on the tasks and associated risks; approval by a safety specialist is recommended.
- When there is a risk of ignition from static electricity, wear anti-static protective clothing including overalls, boots and gloves, in accordance with EN 1149.
- Choose appropriate footwear and additional skin protection based on local risk assessment.
Respiratory protection
- Select a respirator that meets the appropriate standard or certification, based on hazard and exposure potential.
- Use a respirator conforming to EN140 fitted with an A/P2-type filter or better, within a suitable respiratory protection program (fit, training and correct use).
- Dry sanding, flame cutting and welding of the dry paint film will generate dust and/or hazardous fumes; wet sanding/flatting should be used wherever possible. If adequate local exhaust ventilation is not feasible, use suitable respiratory protection.
Environmental exposure controls
- Emissions from ventilation or process equipment must comply with environmental protection legislation.
- Where necessary, use fume scrubbers, filters or engineering modifications to reduce emissions.
