What is INTERSMOOTH 360 SPC and why choose it?
INTERSMOOTH 360 SPC from International Marina is a high performance, TBT free, self polishing copolymer (SPC) antifouling coating based on patented copper acrylate technology. It is a solvent-borne exterior paint specifically designed for coastal vessels and for use during maintenance and repair. By combining a controlled self-polishing mechanism with effective biocidal protection, it helps reduce fouling on immersed hull surfaces and maintain coating performance over time, in full compliance with the International Convention on the Control of Harmful Anti-fouling Systems on Ships (AFS 2001).

Surface preparation and system compatibility
- Use in accordance with standard Worldwide Marine Specifications.
- All surfaces should be clean, dry and free from contamination.
- High pressure fresh water wash or fresh water wash as appropriate, removing oil, grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.
- Major refurbishment: Always apply over a recommended primer system. Primer surface must be dry and free from contamination. Apply INTERSMOOTH 360 SPC within the specified overcoating interval of the primer. Breakdowns and damaged areas should be prepared to the specified standard (e.g. Sa2½, ISO 8501-1:2007) and re-primed before application.
- Repair over self: Clean entire area by close high-pressure fresh water washing using a fan-jet lance (3000 psi, 211 kg/cm²) as soon as the vessel enters dock and before drying. Repair corroded areas with the recommended anticorrosive primer system, then apply INTERSMOOTH 360 SPC within the primer overcoating interval.
- Over existing TBT-free antifoulings: For application over International Paint TBT-free antifoulings, INTERSMOOTH SPC or competitive antifoulings, specific recommendations must be obtained from International Paint.
- North American surface preparation: SSPC-SP10 may be used in place of Sa2½ (ISO 8501-1:2007) where applicable.

Section 8 – Personal protective measures
The following information summarises the key individual protection measures indicated in the Safety Data Sheet for INTERSMOOTH 360 SPC Black. Selection of PPE must always be based on a site-specific risk assessment.
General hygiene measures
- Eating, drinking and smoking should be prohibited in areas where the product is handled, stored or processed.
- Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory, and at the end of the working period.
- Use appropriate techniques to remove potentially contaminated clothing. Wash contaminated clothing before reuse.
- Ensure that eyewash stations and safety showers are close to the workstation.
Eye and face protection
- Use safety eyewear complying with an approved standard when a risk assessment indicates potential exposure.
- Where contact with splashes, mists, gases or dusts is possible, wear chemical splash goggles and/or a face shield.
- If inhalation hazards exist, a full-face respirator may be required instead of goggles.
Hand protection
- Wear chemical-resistant, impervious gloves complying with an approved standard whenever handling the product, as indicated by a risk assessment.
- For prolonged or frequently repeated contact, use gloves with protection class 6 (breakthrough time > 480 minutes according to EN374). Recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact, use gloves with protection class 2 or higher (breakthrough time > 30 minutes according to EN374). Recommended material: nitrile, thickness ≥ 0.12 mm.
- Replace gloves regularly and whenever any sign of damage or degradation is observed. Note that glove performance can be reduced by physical or chemical damage or poor maintenance.
Skin and body protection
- Select protective clothing based on the specific tasks and risks, and ensure it is approved by a specialist.
- When there is risk of ignition from static electricity, wear anti-static protective clothing. For maximum protection, clothing should include anti-static overalls, boots and gloves (refer to EN 1149 for requirements and test methods).
- Use appropriate footwear and any additional skin protection measures as required by the risk assessment.
Respiratory protection
- Use only with adequate ventilation. Where engineering controls cannot maintain exposure below recommended limits, wear respiratory protective equipment.
- Based on hazard and potential exposure, select a respirator meeting appropriate standards or certifications, used within a respiratory protection programme ensuring correct fit and training.
- Recommended: respirator conforming to EN140 with type A/P2 filter or better.
- Dry sanding, flame cutting and/or welding of the dry paint film generates hazardous dust and fumes; wet sanding or flatting should be used wherever possible. If exposure cannot be avoided by local exhaust ventilation, suitable respiratory protection must be used.
Environmental exposure controls
- Check emissions from ventilation and process equipment to ensure compliance with environmental protection legislation.
- Where necessary, use fume scrubbers, filters or engineering modifications to reduce emissions to acceptable levels.
