What is SEAJET BIOCLEAN ECO CLEAR and why choose it?
SEAJET BIOCLEAN ECO CLEAR is a biocide-free, silicone foul-release coating designed for underwater hulls. It forms a special low-adhesion film that limits the attachment of fouling in both fresh and salt water. Any growth that does appear is only loosely attached and can be removed easily by water movement or simple washing with a sponge, helping to keep the hull clean with minimal maintenance.
Main features
- Biocide-free technology: foul-release coating based on silicone, without biocides.
- For underwater hulls: suitable for long-term protection against fouling in fresh and salt water environments.
- Clear finish: transparent coating (colour: clear).
- Easy cleaning: fouling can be removed by water movement or by hose and sponge, leaving the coating like new.
- Self-recoatable: SEAJET BIOCLEAN ECO should only be repainted with SEAJET BIOCLEAN ECO.
- Compatible substrates: for use over suitably primed GRP, wood, steel and aluminium.
- System product: applied over SEAJET TIE COAT as the preceding coating.
- One-pack product: no mixing ratio calculation required.

Applications and use cases
Recommended areas of use
- Underwater hulls operating in fresh water.
- Underwater hulls operating in salt water.
- Vessels where a biocide-free, foul-release solution is required.
Surface preparation and application guidelines
New application
- Ensure the substrate (GRP, wood, steel, aluminium) is suitably primed.
- Apply SEAJET TIE COAT according to the system specification.
- When using SEAJET BIOCLEAN ECO for the first time, apply 2 coats over SEAJET TIE COAT.
Re-coating over old SEAJET TIE COAT
- Wash and degrease the surface.
- Repair only damaged areas by carefully abrading with P-180 abrasive paper.
- Wipe the abraded area with thinner and touch up with SEAJET TIE COAT.
- Apply two fresh coats of SEAJET BIOCLEAN ECO.
Cleaning in service
- SEAJET BIOCLEAN ECO limits the adhesion of fouling due to the special properties of its film.
- For removing any fouling growth, use a light pressure wash or clean by hose pipe and sponge.
- This method avoids damaging the coating and leaves it looking like new.
Important application notes
- Due to the presence of silicon compounds, contamination of other areas by overspray should be avoided, as it can result in failure in those areas.
- Brushes, rollers and spray lines should be dedicated to this product or be discarded after use.
- Mask areas close by to avoid overspray.
- In static conditions, expected performance depends on trading pattern and environmental conditions such as fouling activity, pollution levels and water temperature at the static location.
- In case of brush or roller application, more layers may be required to achieve the specified film thickness (values given are based on roller application).
FAQ
-
Is SEAJET BIOCLEAN ECO CLEAR an antifouling paint?
No. It is a biocide-free silicone foul-release coating that works differently from traditional antifoulings by limiting the adhesion of fouling.
-
On which substrates can I apply SEAJET BIOCLEAN ECO CLEAR?
It is suitable for use over suitably primed GRP, wood, steel and aluminium when applied over SEAJET TIE COAT.
-
What primer should I use before applying this product?
The specified preceding coating is SEAJET TIE COAT.
-
How many coats are recommended for a new application?
When using for the first time, apply 2 coats of SEAJET BIOCLEAN ECO over SEAJET TIE COAT.
-
Can I recoat SEAJET BIOCLEAN ECO with another product?
No. SEAJET BIOCLEAN ECO should only be repainted by itself.
-
How do I clean fouling from a hull coated with SEAJET BIOCLEAN ECO?
Use a light pressure wash or clean with a hose and sponge. Fouling is only loosely attached and can be removed easily.
-
What are the recommended application conditions?
Apply between 5°C and 35°C ambient and product temperature, with substrate temperature between 7°C and 35°C and maximum relative humidity of 85%.
-
How long must I wait before launching the vessel?
At 5°C, 10°C, 20°C or 30°C, the minimum time before launching is 1 day, based on a dry film thickness of 100 µm.
-
What thinner should be used?
Use SEAJET THINNER A. For airless spray, the thinning range is 0–1% by volume.
-
How should I handle overspray risk?
Mask nearby areas carefully and dedicate brushes, rollers and spray lines to this product, or discard them after use, to avoid silicone contamination of other surfaces.
