4. Low VOC Eco-Friendly Formula Meets international environmental regulations, reduces hazards to operators and marine environment.
5. Wide Substrate Compatibility Works on metal, glass, plastic and more; ideal for high-precision and high-standard surface treatment projects.
6. Simplified Construction Process Revolutionizes the complicated application process of traditional dense anti-fouling paints, improving practicality and commercial value.

Low-Pressure 5 Bar NANO AM Coating for Ship Hulls

The coating adopts visible-light excited nitrogen-doped carbon modified titanium dioxide (NANO AM) technology, bringing revolutionary marine anti-fouling performance: ✅ IMO Compliant Non-Toxic Anti-Fouling No copper, organotin or harmful biocides. Under visible light, NANO AM generates reactive oxygen species (ROS) to break microbial cell metabolism. Fully satisfies the IMO Convention on Harmful Anti-Fouling Systems. ✅ Prevents Biofilm & Organism Attachment Photocatalytic reactions decompose organic secretions from algae, inhibiting biofilm formation and drastically reducing barnacle, oyster and marine organism adhesion. ✅ Optimized Low-Pressure Spraying (5 Bar) Far lower than conventional 10–20 bar high-pressure spraying. Less atomization loss, higher coating density, lower porosity and enhanced corrosion resistance. Perfect for complex curved hull surfaces. ✅ Wide Visible Light Response Range Nitrogen & carbon co-doping extends light response wavelength above 500 nm. Maintains photocatalytic activity under cloudy weather and dim underwater environments for sustained anti-fouling effects. ✅ Ultra-Long Service Life & Economic Benefits Maintains stable anti-fouling performance over 2 years in simulated seawater, compared to only 6 months for conventional coatings. Cuts dry-dock maintenance frequency. Smooth hull surface lowers navigation resistance, saving 5%–8% vessel fuel consumption. ✅ Customizable Composite Formula Can be compounded with graphene and silane coupling agents to boost mechanical strength and superhydrophobicity (contact angle＞150°), integrating self-cleaning, anti-corrosion and anti-fouling functions. ✅ Adaptable to Low-Light Areas For hull zones with weak light penetration such as keels, trace persulfate additives enable non-photocatalytic oxidation to reinforce anti-fouling performance.

Working Principle of NANO AM Photocatalytic Anti-Fouling

1. Photocatalytic Oxidation Reaction (PCO) Under visible light (400–550 nm), NANO AM generates electron-hole pairs to produce hydroxyl radicals, superoxide radicals and hydrogen peroxide. These active oxidants destroy microbial membranes, disrupt biofilm EPS and restrain marine larval attachment.
2. Physical Superhydrophobic Defence 10–50 nm NANO AM particles construct micro-nano composite surface structure with contact angle over 150°, lowering initial biological adhesion. High specific surface area (>200 m²/g) provides abundant active catalytic sites.

Performance for Yacht Anti-Fouling

• Static Anti-Fouling: Activates under low brightness (5000 lux, cloudy daylight). Real test in Hong Kong: barnacle adhesion area below 5% after 30 consecutive rainy days.
• Dynamic Anti-Fouling: Organic-inorganic hybrid silica network improves coating hardness. 40% higher self-cleaning rate during navigation, protecting core catalytic layer from propeller turbulence erosion.
• Green Environmental Protection: Low heavy-metal formula eliminates sediment pollution in harbours. Photocatalysis decomposes oil contaminants, reducing demand for hull chemical cleaners.

Traditional anti-fouling coatings require frequent dry-dock cleaning. NANO AM photocatalytic technology combines photocatalytic oxidation and physical surface protection to achieve 2+ years static anti-fouling with nearly zero heavy metal pollution, creating a new benchmark for yacht and ship maintenance.

Usage Guidelines

Specification

• Net Volume: 450 ML per can

Operation Steps

1. Preparations Shake the aerosol vigorously for minimum 20 seconds. Wear sealed mask and protective clothing.
2. Spraying Instructions Use the full can continuously to avoid nozzle clogging. High-speed vessels: Apply 2 coats; wait for full drying between layers. General application: Single coating thickness controlled below 50 μm.
3. Drying & Launch Requirements Environment relative humidity ≤55%. Wait 2 hours after spraying before launching. Do not store coated hull in dry dock for more than 30 days.

Storage & Safety Notice

• Store below 40°C, avoid direct sunlight and open flame. Do not puncture or incinerate cans.
• Wear complete protective gear during construction.
• Dispose empty cans according to local hazardous waste regulations.

Troubleshooting Tip

If nozzle clogs, clean with dedicated solvent or contact supplier for technical support. Strictly follow operating specifications to guarantee coating performance.
