What SEA GRANDPRIX 2000 A is and why choose it
SEA GRANDPRIX 2000 A from Chugoku is a high-performance hydrolysis antifouling paint based on a special silyl methacrylate polymer. It is designed to protect the underwater hulls of steel ships operating in coastal service, including vessels with low activity or slow steaming in high-risk fouling areas. Controlled hydrolysis and a high-activity polymer matrix ensure efficient biocide release, long-term antifouling performance and excellent protection under static conditions. The product is compliant with the IMO Anti-fouling Systems Convention (AFS/CONF/26 & IMO MEP.331(76)) and is intended strictly for professional use.
Main features
- Special silyl methacrylate hydrolysis technology: provides controlled surface activation and sustained antifouling protection aligned with the applied film thickness.
- High-performance antifouling: high active polymer content maximises biocide effectiveness and leaching control, delivering long-term fouling protection.
- Excellent static performance: specifically formulated to maintain antifouling efficacy in static or low-activity conditions when environmental parameters are suitable.
- IMO AFS Convention compliant: does not contain organotin compounds acting as biocides and complies with international anti-fouling regulations.
- Professional-grade application window: suitable for airless spray, brush or roller, with clear guidelines for thinning, film thickness and environmental conditions.
- Compatible system build-up: can be applied over appropriate existing antifoulings and primers such as SILVAX SQ-K and CMP AC, after correct surface preparation.
- Multiple colour options: Light Red H, Red H, Blue H and Black H for flexible hull marking and inspection.

Surface preparation and system compatibility
- Substrate: Underwater hulls of steel ships.
- Surface cleanliness: Remove all contamination such as dirt, grease and oil.
- Existing coatings: To be used over suitable existing antifoulings and primers; compatibility should be confirmed with a CMP representative.
- Water washing: Close high-pressure fresh-water washing up to 250 bar (3500 psi) to remove contamination and leached layers from existing antifouling prior to application.
- Preferable preceding coats: SILVAX SQ-K, CMP AC and compatible primers.
Applications and use cases
- Coastal cargo vessels: Steel-hulled coasters, feeders and short-sea traders requiring reliable antifouling during frequent port stays and slow steaming.
- Low-activity and lay-up scenarios: Vessels with intermittent operation or static periods in high fouling risk locations, where excellent static performance is required.
- Workboats and service craft: Tugs, supply boats and harbour craft operating mainly in coastal and harbour waters.
- Dry-docking maintenance: Renewal or maintenance of existing compatible antifouling systems after appropriate cleaning and inspection.

Section 8 – Individual protection measures
The product is restricted to professional users. Personal protective equipment (PPE) must be selected and used according to local regulations and the Safety Data Sheet.
Engineering controls
- Provide adequate general and local exhaust ventilation to keep solvent vapour and particulate concentrations below occupational exposure limits.
- During spray application in booths where ventilation may be insufficient, operators should use a compressed air-fed respirator until solvent vapour and particulate levels are below exposure limits.
Respiratory protection
- When airborne concentrations may exceed exposure limits, use a half-mask respirator to EN 140 fitted with a combined particulate and vapour filter to EN 14387 with an assigned protection factor of at least 10 (e.g. A2P3).
- During dry sanding, flame cutting or welding on the dry film, use suitable respiratory protection if effective local exhaust ventilation cannot be provided; wet sanding is preferred wherever possible.
Hand protection
There is no single glove material that provides unlimited resistance. For repeated or prolonged contact, use gloves tested according to EN 374. Recommended options include:
- High protection (> 480 min permeation): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm).
- High protection (240–480 min): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm).
- Medium protection (120–240 min): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm).
- Medium protection (60–120 min): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm).
- Short-term/splash protection (30–60 min): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm), Nitrile gloves (0.31 mm).
- Short-term/splash protection (10–30 min): Polyethylene (PE) gloves (0.062 mm), Butyl/Viton gloves (0.70 mm), Butyl gloves (0.3 mm), Neoprene gloves (<0.4 mm), Nitrile gloves (0.175 mm).
Non-suitable gloves (permeation <10 min, non-exhaustive): natural rubber gloves (0.75 mm), nitrile gloves (unspecified), neoprene gloves (0.75 mm), PVA gloves (0.2–0.3 mm).
Follow glove manufacturer instructions for use, maintenance and replacement. Replace gloves regularly and immediately if any damage is observed. Use PE under-gloves in high-exposure or uncertain chemical situations.
Eye and face protection
- Wear safety eyewear to EN 166 designed to protect against liquid splashes (e.g. safety goggles or face shield).
Skin and body protection
- Wear anti-static protective clothing made of natural fibre or high temperature resistant synthetic fibre.
Environmental protection measures
- Prevent product, overspray and cleaning residues from entering drains or watercourses.
- Carry out application, maintenance and repair on impermeable, contained surfaces so that all spillages and waste can be collected for reuse or disposal.
