SeaQuantum Spectrum S is an antifouling, in the acrylic coating system. The product is designed to work under static conditions, hydrolysing rapidly once the ship starts sailing. Through highly predictable and stable self-polishing properties, it reduces the risk of fouling during outfitting and long idle periods. Parameters on this page: volume solids 58 ± 2%, dry film thickness 50-125 µm, theoretical spreading rate 11.6-4.6 m²/L. Comparable models from the same brand: SeaMate M, Seamate NB, SeaQuantum Classic III.
Parameter source: JOTUN original technical data sheet (TDS) for SeaQuantum Spectrum S (methacrylic silane low-friction self-smoothing antifouling for mooring (S)); spreading rate and other values are converted from TDS parameters and provided for product selection reference only.

SeaQuantum Spectrum S
It is a one-component hydrolytic methacrylic silane antifouling. It provides excellent antifouling protection even in challenging fouling environments. Through highly predictable and stable self-polishing properties, it reduces the risk of fouling during outfitting and long idle periods. Used only as the final coat in immersed environments. It improves UV colour resistance and colour stability. Suitable for overcoating other Jotun antifouling surfaces. It can be applied at surface temperatures below 0 °C.
Marine coatings:
Recommended for the underwater areas of newbuildings. Designed as a high-performance solution for ships during outfitting, primarily for fouling protection. The product is designed to work under static conditions, hydrolysing rapidly once the ship starts sailing.
Industrial protective coatings:
Recommended for immersed areas of offshore structures and fixed installations.
As a newbuilding antifouling, providing protection during the outfitting stage.
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.
