INTERNATIONAL MARINE COATINGS EXTENDS SILICONE ANTIFOULING RANGE

Jun 2, 2026 | Marine coatings & hull protection news

AkzoNobel’s marine coatings brand, International, has launched a new silicone foul-release coating, Intersleek 2120, designed for the operational and regulatory realities of today’s fleet.

Intersleek 2120 expands access to the proven silicone technology from International for vessel operators, delivering reliable, predictable performance aligned with day-to-day operating conditions. Built on three decades of silicone experience and real-world operational insight, Intersleek 2120 is engineered to support lower total cost across the docking cycle, through reduced application and maintenance. 

While silicone foul-release technology has historically been adopted in more specialised vessel segments, a broader group of owners can benefit from silicone-based performance when the solution is aligned to their operating profile, service needs and value expectations. Intersleek 2120 is designed for vessel operators transitioning from biocidal self-polishing copolymer (SPC) systems who are seeking to improve hull performance in response to increasing regulatory and efficiency pressures. Delivering speed-loss performance of up to 1.4%, it is considered suited to vessels such as bulkers and tankers, as well as a wider range of vessel types and operating profiles.

According to International, with off-hire and drydock costs running into tens of thousands per day and millions per docking, the right coating can play a role in reducing time in dock and controlling overall costs. Compared to established industry silicone systems, Intersleek 2120 is said to require fewer coats within the overall scheme, reducing application time and associated drydock costs. By aligning this performance more closely with real operating conditions, Intersleek 2120 helps operators avoid unnecessary scheme complexity and maintains the core benefits of silicone foul release technology.

Daniel Stapleton, Marine Deep Sea Marketing Manager, said: “For 30 years, Intersleek has defined what silicone foul release technology can achieve for the maritime industry. With Intersleek 2120, we are extending that trusted platform to a broader range of operators with a solution that is designed around their operating profile, performance and value expectations.”

Intersleek 2120 is available globally and joins International’s marine coatings portfolio which includes the flagship silicone foul-release solution, Intersleek 1100SR. AkzoNobel can provide shipowners and operators with a bespoke performance forecast using Intertrac Vision, its data prediction platform that identifies the most suitable coatings choices, including the Intersleek range, for each vessel.
