Actiguard technology

Groundbreaking technology that integrates hydrogel and biocides in a single coating. 

ActiGuard® is the result of years of research and development to produce a single hull coating based on a silicone-hydrogel blend that can store and diffuse a sufficient volume of biocide to last over an extended period of time, while preserving the long-term stability and mechanical properties of the coating.

Hydrogels consist of a network of polymer chains that instead of dissolving in water actually absorb water to a level of more than 99 per cent. This gives them the capability to minimize protein and bacterial adhesion.

An active hydrogel microlayer forms a barrier between the solid silicone binder and fouling organisms. This establishes a highly effective Fouling Defence barrier with a significantly longer effect than conventional Fouling Control solutions. The result is a clean hull for an extended period with on average 6% fuel savings over a 60-month docking interval.
