SeaQuantum Ultra III ) is an antifouling paint of the acrylic coating system. As part of a complete coating system, the product provides long-term protection of up to 90 months. This antifouling effect is achieved through highly predictable and stable self-polishing characteristics, while reducing hull deterioration, friction and speed loss. Parameters on this page: volume solids 54 ± 2%, dry film thickness 75–175 µm, theoretical spreading rate 7.2–3.1 m²/L.

SeaQuantum Ultra III
Silyl Methacrylate Low-friction Self-polishing Antifouling Paint III(U) (6GM)
This is a single-component, chemically hydrolysing methacrylic silane antifouling coating based on new technology, providing high antifouling protection, low frictional resistance and self-smoothing hull properties. The antifouling effect is achieved through highly predictable and stable self-polishing characteristics, reducing hull deterioration, friction and speed loss. The initial smooth surface provides good dry-docking properties. For use as a topcoat in immersed environments only. May be applied at surface temperatures below 0 °C.
Marine coatings:
Recommended for underwater hulls on newbuildings and at dry-docking. Provides an optimised solution for low-trading-frequency and slow vessels. Recommended for areas requiring good antifouling, such as sea chests, to reduce the risk of invasive species. The product provides optimised hull protection for vessels in heavy fouling waters or with long idle periods. As part of a complete coating system, the product can provide long-term protection of up to 90 months.
Industrial protective coatings:
Recommended for immersed areas of offshore structures and fixed installations.
Designed for global service, particularly the coastal industry. May come into contact with seawater and fresh water when used during newbuilding outfitting.
Antifouling.
Complies with the IMO Antifouling Systems Convention AFS/CONF/26 and IMO MEPC.331(76)
Other certificates and approvals are available on request.

In some markets, the stated shelf life may be shortened to comply with local legal requirements. The above is the minimum shelf life; thereafter, testing is required to confirm quality remains acceptable.
For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
The information in this datasheet is based entirely on knowledge gained in our laboratory and in practice. JOTUN products are regarded as semi-finished products, and their use is generally beyond our control. JOTUN therefore guarantees only the quality of the product itself. To comply with local regulations, the product may be adjusted, and we reserve the right to modify the datasheet without further notice.
