SeaQuantum XT
SeaQuantum XT is a single-component chemically hydrolysing silyl methacrylate antifouling coating employing advanced technology, providing protection performance for vessels in high-fouling environments.
SeaQuantum XT is derived from the proven silyl and silyl methacrylate resin antifouling technology of the SeaQuantum series, which has completed more than 20,000 applications worldwide.
SeaQuantum XT incorporates ActiCore™ core technology — a unique patented resin technology combined with an optimised biocide combination to provide consistent algae and slime protection. The coating forms an ultra-smooth initial surface and provides full-cycle performance. It offers highly predictable and stable self-polishing performance and provides in-service performance.
Application of SeaQuantum XT shall follow the instructions in the JOTUNHPS (Hull Performance Solutions) workflow.
For details, consult your local JOTUN office.

For the maximum recoat interval, refer to the Application Guide (AG) for this product.
The dry/cure-to-immersion data in the table above are the times required before the product can enter service. For baffles and similar equipment, longer drying times are required. Refer to the application procedure for further advice.
At higher film thicknesses, the antifouling film stays soft longer. To ensure hull roughness readings, doubling the minimum immersion time is recommended when two or more coats of antifouling are applied in rapid succession.
Drying and curing times are determined based on temperature and relative humidity below 85%, with dry film thickness within the average range.

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.
